Julius Caesar learn about a portal leading to your setting, and is ready to start a full planar invasion...

That actually never happens in the lore, reminder that Thay got their shit kicked in by a !not-mongol Horde whose highest level caster in PnP is a 10th level cleric.

See Gate: And thus the jsdf fought there

If it's the realms, the last guys who did it just ended up importing their pantheon and founding new countries.

A) Be BTFO by guns

B) Be BTFO by crazy cannibals

C) The last of the humans bow before Ceaser and they merrily slaughter savages side-by-side.

The who?

wether he wins or loses...
this needs a caption

what?

The setting I made or the one I'm playing? The first is medieval fantasy, the second is JoJo

Julius Caesaer launches a grand invasion into the Other World. Initial success is had as it seems the armed forces of the local political groups are mostly depleted, and the nobility that can be reached are easily willing to bend the knee in return for protection. The culture seems remarkably similar, although metalurgical advances of this Other World is slightly advanced. Had everyone not been mostly dead from plague and war, perhaps the Empire could have been challenged?

The new lands allow the Roman Empire to import more grain, export more farmers and - in a genius bid - the disgruntled legionaires who had served under Caesar his in Gallic campaigns and during the Civil War can easily be re-settled in the vast interiors of a climate that's mostly like Italy. This curtails civic discontment, allows Caesaer to bribe the people with more free stuff (land and grain!) and hydras are probably one hell of a hit in the arena, those few who can be captured.
Having taken control over the Pytheria States, Caesar is declared Augustus twice-over. All is well. His meglomania increases.

He is assassinated.

The Roman Empire descends into chaos, but without the lynch-pin of the Egypt grain supply and the need to placate Cleopetra and Ptlomaemaic Egypt to ensure continued trade, Mark Antony can instead flee to Pytheria through the portal (which I imagine is easily defended once fortified).
eventually
It's an interdimensional roman civil war with the exhaused Pytherian city-states once again getting the short end of the stick.
Approximately 6 years after the Invasion, the Singing Plague returns. Romans from Earth do not have Herd Immunity, do have a high population density and aren't familiar with magic. Probably 70-80% mortality rate, both planes.

Let's call it a late game win for the Fallen Stars, but a good show on the Romans side.

>What happens?

>Day one: This land is incredible, but confusing. A veritable army of small mechanical creatures toddles around our scouts, offering them dried and rotted food. At first we thought this a trick, but the creatures seem genuinely unable to understand that we do not wish to partake of their offerings. Still, they have been very helpful, able to work without pause setting up our camp.

>Day two: Some of the creatures have begun showing our scouts features of the local area. Many strange devices and machines have been discovered, although our hosts seem confused that we do not understand the devices' purposes, and believe that we are their creators. Their attempts to trick us into consuming their offal have become more devious.

>Day three: Several of our scouts have reported becoming ill, and their hair falls out as though they are old men. Our hosts are unable to explain the malaise, but have redoubled their efforts to goad us into eating what they claim is food.

>Day four: I awoke this morning to the taste of blood in my mouth, and discovered that several of my teeth had come out in the night. All my men are similarly afflicted. Fourteen have died from mysterious bleeding, and we are all very ill. Coming to this place was a mistake. Our hosts seem unwilling or unable to understand our concerns, despite the zeal with which they claim to desire becoming our servants.

>Day five: All my men are dead. This world is a poisoned heart, and we are poisoned for daring to trod upon it.

>Fairie the Lost game
If the modern world of darkness, he gets fucked because of tech advantage.
If into the Fairie lands, he's more than fucked.
>Forgotten Realms
forgotten Realms
>5th ed game
kinda like Though it depends upon if he finds a useable bit of the Lost Age of Magic and what he does about it.

He gets rekt and counterinvaded, entire Earth is then enslaved.

Good luck, I'm behind 700,000 steppe nomads.

Heeeey, nuclear apocalypse, all right!

He stumbles into a universe where the Roman State has survived into the Pike and Shotte era.

Outside of Christianity, he probably rolls with it.

>Caesar stumbles into a setting where the Roman State survived into the musket and early rifle era
>Napoleon and his armies stumble into this same setting
Place your bets.

Personally, my bet is on Napoleon acting like the massive Romaboo he is and teaming up with Caesar

>Anima
He'll probably wreck some chaos for a while until someone of level 6 or above comes and slaughters his army.
If a particularly sadistic wizard is around somewhere and is aware of the invasion, he may redirect the portal to Moth and watch the unfolding horror.

They get wiped out by swarms of random monsters just like the rest of humanity.

Setting I'm working on:

Probably fucked because I based the empire in it a bit like the old Roman Empire, but into late Medieval technology and low level magic.

But it might be a good fight, as the empire just got wrecked pretty hard in an huge war 80 years back, and is big fragmented right now. If Caesar allied with one of the more rebellious Great Cities, he might be a deciding force in the war.

>Caesar and Napoleon decide the want to team up and conquer the multiverese
>Team up with Alexander, Genghis, and Khalid al-Walid on their way

Can the greatest military minds in human history conquer the multiverse?

he sees this and then his army is just wiped out in one encounter.
then the party asks what the fuck was with the easy fight

if you're assuming without party intervention, the same but with less shenanigans and more professionalism.

He and his army get sold stuff. Possibly "authenic" roman memorablia.

Image source?

Assuming they can find a few greedy mages or the like to support their cause, things probably go well. This would also mean more stability for Rome, as the Emperor could live in a world with a bunch of healing magic.

...

Dunno. Found it in a random google search months ago.

Nothing in the resolution I posted, but the DevArt account seems legit; there are other posts with similar armor styles.

"How convenient! The names of these places are in latin! Granted, it's a kind of bastard latin, and- wait... these people are Germans? Well, at least they don't style their hair with rancid butter."

The first skirmish would be a blood bath. Musketeers would set up a volley line and engage at 100 yards. The invasion would probably fall apart once the Grand Kingdom put together a full army with artillery and mounted support, and that's not taking magic and hero agents into account.

>Julian the Apostate could have not died so young with magic
>we live in a world without magic

The portal opens near a city. The SWAT officers singlehandedly wipe out the mysteriously murderous people who are pouring out of the portal.

>"How convenient! The names of these places are in latin! Granted, it's a kind of bastard latin, and- wait... these people are Germans?"
Oh Caesar, you and I are going to have a field trip with these "Romans"

Does pretty well at first, conquer a few villages and towns. Wrecks the !not-Arabs (if he lands in the desert) and is allowed to live in peace. If he attacks a major civ, he gets BTFO by combined armies of !not-Kievan Rus, !not Wales, !not-Ameri-Rome, !not-England, !not-Germany, !not-Mongolia, and !not-Italy. The Inquisition and Magicians also help.

This is stupid and the question is shit, but this gives me an idea. My D&D group will now soon be traveling to the elemental plane of Rome!

They get a citation for unauthorized use of a dimensional portal. Their court date's in a week, and they face a hefty fine.

>legion get's infected
>undead legion

Depends which planet he lands on.

>running an EP game
>portal opens up into post-fall Italy

Hoo boy. The first and most pressing dangers will be the nuclear winter, exposing the legions to freezing temperatures, a dearth of food and non-contaminated water, and high levels of ionizing radiation which will lead to radiation poisoning if they somehow manage to survive for longer than a month.

Which they won't, not in large numbers anyway, given that a single TITAN war machine could rip through the legionnaires by the thousands and leave the rest mortified that they are fighting a mechanical god. Rogue nanomachine clouds will strip a given element from anything it passes over - one century will flop to the ground as the calcium is harvested from their skeleton, another will shrivel into stacks of dried protein as all of their water is taken, etc.

If there are any that survive even that, they will be infected by the exsurgent virus and, for a time develop reality0bending powers before they metamorphosize into the chimeric echoes of long extinct and subsumed aliens.

Except for one runner.

He'll make it back through the portal, speaking of a hell of frost and steel and eating dust. They will close the portal for ever, and after this one messenger will drop an virus-laden tear into an aqueduct and doom humanity in that timeline.

...

He and his army get flattened by orbital bombardment.

Assuming the portal he found leads to the one city that remains intact (thus avoiding being ripped apart at the atomic level the instant he stepped through the portal)?

Well, since I assume his men don't have full body suits of any kind, after a few hours about 75% of his forces succumb to a strange sickness that leaves them convulsing on the ground for anywhere from a few minutes to several hours. Then 50% of those men die, 48% of them become near-mindless savages driven only by instinct, 1% of them become massive monstrosities that want to kill all living things, and the final 1% become immune to the sickness and find their capabilities and skills greatly enhanced.

Aside from all that, they find themselves in the twisted, jumbled remains of a city where all of this has already happened to most of the population (hundreds of thousands). The landscape is warped, nothing where it's supposed to be, and the layout of the city seems to change whenever you're not looking, making reliable navigation almost impossible. Hopefully a few of those who survived the sickness without being corrupted by it also survived the bloodbath afterward, since they're the only ones that can find their way. The technology is vaguely "early industrial", though with everything gone to shit there isn't much to be found that works.

Assuming the entire Roman army doesn't tear itself apart when it first succumbs to the sickness, the few that remain might eventually find the small enclave of survivors near the center of the city (I say might because, again, the city is hell to navigate), in a heavily fortified and decently stocked base. If they're smart, they'll join up in the interest of mutual survival. If they attack instead, they'll get mowed down by the enclave's firearms, wasting the majority of the enclave's stockpiled ammunition and making life a bit harder for the people that need that ammunition to protect themselves while scouring the city for supplies.

>after a few hours about 75% of his forces succumb to a strange sickness

Just to be clear, the other 25% will still succumb to this sickness at some point, it will just take longer, as a small portion of the population seems to have some amount of resistance to it.

>All these faggot teenagers going on about how badass their setting is

They die to horrible magic they can't comprehend, and professional armies that use firearms and dinosaurs?

>Being upset that some people play sci-fi or high magic fantasy games

>Basically Wild Cards, on a custom not!Earth with some fun subtle magic thrown in for shits and gigs.
Honestly, putting the Legions against even a mundane Old West setting will fuck them over. Much less one with magic.

Depending on the planet, technology ranges from none to early machine age. So he would either have a real easy time or get torn apart by artillery. If he adapts and manages to use both technology and magic he could probably start a decent empire.

A big fat mistake on their part

High magic, which you may as well throw in sci-fi in there too because it pretty much is, is a setting for idiots and simpletons. People that can't figure out how to make something creatively without shrugging and mumbling "magic did it".

He'd ruin everything for everyone by breaking the already landed empire's focus from holding off the Rotwood infection that plagues the land, allowing said growth to fester and take over the plane.

GG Caesar.

How large was the entirety of the roman army? Because the crab people in my setting are numerous at the time of my current campaign.

Qwp

Brutus stabs him, unfortunate timing for this portal i must say

>evil waifu hoarder
Found my next BBEG

the idles of march happens

Depends on how old he is and how quickly he gets some magic going for him. Also where he comes out. Assuming he came out in a relatively isolated area and was able to get himself some wizards. I notice a lot of people bringing up magic, and i guess depending on setting it could make a pretty big difference, but realistically a few magic casters aren't worth that much. I mean i know that wizards and whatnot kill most fighting classes at high levels, but even then you throw enough dudes with swords and spears at them and they loose. Furthermore how many uberpowerful wizards are their really? They tend to be pretty uncommon. Weaker practicioneers wouldn't pose that much of a threat to a large organized army. It would probably come down to how strong the organized military of the setting is, and typically most settings have pretty disorganized and fragmented leadership, cause that makes it easier for the pc's to be special snowflakes and go around being heroes. I don't think he'd be able to do much more than take a foothold. I don't think he'd conquer the whole setting, but it could happen i suppose. Man will do anything to get his wheat.

youtu.be/xFxrzSrVv0I?t=168

Depends on the time period of the setting. He'd lose if he came in at any time further along than 700 years into the setting since at that point there are two nations with more manpower and organization than Rome at its peak and half a dozen that are at least a difficult challenge.

If he showed up in the most recent setting a local garrison army of a backwater planetary capital area could wipe his forces with a few hundred tanks, mechs, fighters, a few odd star-ships, and several thousand augmented infantry. Even in melee combat Roman Legions can't face genetically-altered cybernetic troopers with powered armor and vibroblades.

If he showed up in the early days of the setting he could win though. The amount of mass chaos in the beginning of the setting is like the migration period but with three separate species all at once. Throw in a human invasion with actual organization and slightly better tech and the world is his for the taking. It would take decades, but if the entire empire was actually behind him with no traitors and the gift of absolute power he might make it happen.

Jap attack choppers and Ride of the Valkyries. Fucktards sitting on their helmets. Putting random spears into a Ballista. Obligatory insane Loli battle bruiser. Obligatory retarded Genki girl with bullshit fighting skills in the military. Looks like shit.

Engine hearts campaign?

And this also assumes that nobody in the setting actually knows that the portal goes to earth. If they knew that he would lose horribly, because the setting is filled with creatures that used to live on earth but no longer do. If they found a portal on their planet going back they would immediately stop fighting each other and storm back in with a vengeance. When they finally do find earth in my current cannon the only thing that stops them from causing a terran bloodbath is the fact that most species have forgotten about their roots after three millennia away from home and only one species bears a grudge that long.

It's a combination of Jap ultra nationalism and a harem show. That's about it.

>I hate fun! Grrrr!

> Champions setting
Little difficult. On one hand, a few capes or the USDMT could handle it. Portals to wherever aren't that rare (government has one). On the other hand, how long is tge portal open? How easily could a villian use it to go back to Rome? Would any Roman deaths cause time paradoxes? Would Ceasar's? Did this happen and the betrayal was some ancient Roman cover up? Was it a long con by not!Vandal Savage? Find out next week.

>Pokemon setting

The natives are strangers to war. The few with the capacity for lethal violence are villians. One villian sees the ultimate challange, the other a perfect oppertunity. Most people are boned. Wild Pokemon are dangerous, but it'd make sense if the Romans could train them too.

>pokemon + romans

FUCKING CODEX ALERA

GATE: Thus the Adepta Sororita fought there.

My setting is an apocalyptic early middle ages nightmare world where all communication has broken down to city level and the largest governments are counties or baronies. The forests are infested with horrible abominations, raiders descend from the north as they have been evicted by said abominations and seek new lands, and nature itself is seeking the corruption/destruction of sentient life.

Poor Caesar.

He teams up with the already existing Roman army which is fighting battalions of Cowboys.

Not even kidding.

Gauls retake northern europe, persia invades southern empire.

Most likely, they get eaten by grues.

Well, magical beasts, anyways, considering the flatlands are filled with the damn things and have an ecology that would make Deathworlders feel right at home before slaughtering them mercilessly.

what.

Depends on where they end up and who they fight.
Not-Japan would be difficult only because of their island nature and the large population of Dragons present. However, Rome could build enough ships and learn how to take down dragons easily enough.
The main continent has a large collection of small kingdoms and empires, any of which would be easy pickings on their own. However they all have an intricate and convoluted web of alliances, cease-fire pacts and personal ties that once you start a fight, slow the entire region will move against you.
Rome woukd face an endless tide of everything from aloof fae, greedy goblins, prideful humans to the most debased monsters, all set forth to defend their homelands and friends.
To the west are Drow, who are forever stuck in their personal disputes and civil wars. Again, though, any outsiders who would move against them and you'll see every house, every temple and every city band together as one, united and unbreakable force.
Once threats are gone though, straight back to back-stabbing, even as they make their way back to their own homes, they'll be raiding and raping all their neighbours on the way.
Further west still is unknown, dwarves and wild magic lay that way but if this would be easier or harder is unknown.

To the East, across the waters, is Caledonia, an enormous Empire who has claimed more then half the world by this point.
Caledonia though, is slow to react.
Should Rome be sucsessful in taking lots of cannons and procurring the rescipe to gun powder, they can easily build an kingdom for themselves before the Empress even hears of what has happened.
It'd be years before an army was raised to march against them. However small fleets and garrisons are scattered everywhere, so Rome is facing near constant small attacks and forts will grow around them like mushrooms, to keep them hemmed in.
Caledonia would win a drawn out conflict but may be willing to ignore a thorn should it be to difficult to pull out.

gate is shit tho

The ocean itself that lays between is full of scattered islands, atolls and more.
Any single community would be easy to shift or kill and Rome could have most the Ocean to themselves in just a few years.
The worse they would face are Pirates who could be hunted individually or even bought, the Caledonian navy who'll leave them alone as long as their tea, alcohol, gold and slave imports remain untouched and the occasional abyssian sea monster.

Finally to the south is the truely unknown.
No known map exists to that place, and the few who ever travel far enought and return are inconsistant, lava rain and volcanos spewing freezing mists, flying cities and vast, empty, fortresses of stone floating on the waters surface.
It is thought that this is where the gods dwell.

Stop confusing opion with fact.

>opion
opinion.
What the fuck autocorrect?

There is a brief period of immense confusion, followed by a lot of Roman soldiers panicking because holy shit did they just invade Olympus and why is that guy throwing lightning at me?

Basically, the local Society garrison crushes the army with varying amounts of bloodshed depending on where they show up. The world on the far side of the portal falls shortly thereafter, once people are done debating the ethics of interdimensional imperialism.

>The worse they would face are Pirates who could be hunted individually or even bought
Julius Caesar has some experience with pirates.

livius.org/sources/content/plutarch/plutarchs-caesar/caesar-and-the-pirates/

>[2.1] First, when the pirates demanded a ransom of twenty talents, Caesar burst out laughing. They did not know, he said, who it was that they had captured, and he volunteered to pay fifty.

>[2.2] Then, when he had sent his followers to the various cities in order to raise the money and was left with one friend and two servants among these Cilicians, about the most bloodthirsty people in the world, he treated them so highhandedly that, whenever he wanted to sleep, he would send to them and tell them to stop talking.

>[2.3] For thirty-eight days, with the greatest unconcern, he joined in all their games and exercises, just as if he was their leader instead of their prisoner.

>[2.4] He also wrote poems and speeches which he read aloud to them, and if they failed to admire his work, he would call them to their faces illiterate savages, and would often laughingly threaten to have them all hanged. They were much taken with this and attributed his freedom of speech to a kind of simplicity in his character or boyish playfulness.

>[2.5] However, the ransom arrived from Miletus and, as soon as he had paid it and been set free, he immediately manned some ships and set sail from the harbor of Miletus against the pirates. He found them still there, lying at anchor off the island, and he captured nearly all of them.

Can't we just use nukes?
How about Nukes that are immune to magic?

>[2.6] He took their property as spoils of war and put the men themselves into the prison at Pergamon. He then went in person to [Marcus] Junius, the governorof Asia, thinking it proper that he, as praetor in charge of the province, should see to the punishment of the prisoners.

>[2.7] Junius, however, cast longing eyes at the money, which came to a considerable sum, and kept saying that he needed time to look into the case.Caesar paid no further attention to him. He went to Pergamon, took the pirates out of prison and crucified the lot of them, just as he had often told them he would do when he was on the island and they imagined that he was joking.

he'll have to deal with not one, not three, but two armies of tarrasque mechas

so i guess he's fucked
as is everyone

Well, guess Rome now rules the Lapis Ocean then.
They wouldn't have much trouble once they got black powder production up and running and as long as they leave the Caledonian colonies alone, they pretty much have no opposition.
C'est la vie rich and and most culturally diverse region of the world, farewell Pacific Island-expies. You'll all be speaking Latin inside a generation.

>KOTOR-era Star Wars
Bitch please, the Republic did it first and better.

>Cyberpunk set in the 2070s
The last moments of Caesar's army are that of terror as their formations are cut down by what they think of as automatic miniature pilum-throwers that tear through their armour like paper.
Anyone who somehow survives long enough to close in to hand to hand discovers mere human might is no match for cybernetic limbs holding monomolecular blades.
