Hey guys, I'm bored so let's roll up a Chaos Space Marine Warband. Because why the hell not. Roll a d10 for our structure.

Rolled 9 (1d10)

We are a Renegade chapter, with an allied force. Roll a d100 for said ally.

Rolled 88 (1d100)

Our allies are another heretical chapter, who has back door dealings with us. Huh. Ok, roll another d100 for why we fell.

Rolled 45 (1d100)

Ah, we rebelled, originally with good intentions, against the Imperium. Cool. Roll another d100 for our progenitor.

Rolled 1 (1d100)

... Our progenitors are the Ultrasmurfs. Shit. Since there are so many, anyone want to reroll?

Rolled 37 (1d100)

Sure

SHIT ITS STILL THE SMURFS. Oh well, it seems the dice gods will it. Roll a d10 for our devotion for the Ruinous Powers.

Rolled 8 (1d10)

We are highly devoted to them! Good, those always make for interesting ones. Roll a d12 for which deity we worship.

...

Rolled 6 (1d10)

We worship Slaanesh, the Dark Prince! Well, things shall get loud now! Roll d100 for our beliefs.

Rolled 9 (1d100)

We worship the gods above all! Roll a d10 for our demeanour.

Rolled 5 (1d10)

We have been known to have relic equipment from the Horus Heresy, leading us to respect artefacts. Hmmm. Roll d10 for mutations or deficiencies.

Rolled 1 (1d10)

10 get!

dice+1d10

We have a hunger for flesh. We are Hannibal Lecter in SPESS. Roll another d10 for our mental flaws.

Rolled 2 (1d10)

Ok, this time; 10 get!

Rolled 4 (1d10)

We have trouble remembering things and often hallucinate. This is probably a side affect of all the Drigs we do. Roll a d100 for our hero of legend.

Rolled 61 (1d100)

Our hero was an extremely zealous champion or possesed. I personally think it should be a crazy Noise Champion. Roll d100 for what the hero did.

Rolled 31 (1d100)

He did some cool as shit

He killed a great Imperial hero, such as a chapter master or commissar. I am OK with this. Roll a d100 for our home world type.

Rolled 87 (1d100)

We are fleet based! Roll d10 for our combat doctrine.

Rolled 4 (1d10)

Unorthodox Warfare, so basically whatever we feel like at the time. Kewl. Roll a d100 for our special equipment.

Rolled 75 (1d100)

We have unique Daemon Engines! Inb4 Rape Train daemon engine. Roll a d10 for our status.

Rolled 8 (1d10)

We are slightly overstrength! Roll another d10 for why we are so big.

Rolled 2 (1d10)

We merged with a smaller Warband or picked up the remains from a defeated one. Roll a d100 for our allies.

Rolled 22 (1d100)

We are the allies of a specific Chaos Warband or Lord. And now roll one last d100 for who hates our guts.

Rolled 16 (1d100)

A specific Eldar craft world hates us! Fitting, as we are Slaaneshi. So, that's all the rolling done. We have A renegade Ultrasmurfs successor, with loyalist and chaos allies, we rebelled with good intentions, are highly devoted to Slaanesh, have a lot of relic equipment, hunger for flesh, and we have dementia. Our hero was a Zealos champion who killed a great imperial hero. We are fleet based, giving us higher leeway to produce unique daemon engines. We use unorthodox warfare, and are slightly overstrength due to picking up the remnants of a failed Warband. Our actions have caused a certain craft world to hate us. So what can we do with this?

>Rebelled with good intentions.
>Horus Heresy relics.
I say we rebelled shortly after the second founding; we simply didn't like the Codex Astartes and said "fuck it, we can do better without it", or something like that.
Just throwing out ideas.
