Hey TG, i need some feedback on a premise for a dungeon-crawl-focused campaign I'm working on.
About 60 years ago, Kingdom A and Kingdom B were at war. A was losing
The old king of Kingdom A invited a cabal of wizards to offer their magic to the war effort, but before hearing their proposals, died in battle.
His son, still raw with grief, goes to meet the wizards, and is appalled at their proposals, particularly the bit about reviving his father as a swarm of flesh-eating beetles. He declares the wizards enemies of the state and attacks them, although they get away, swearing they'll have their revenge as they leave.
Faced with two foes now, the new king agrees to capitulate to Kingdom B, on condition that Kingdom B declare the wizards enemies as well. Kingdom B agrees, because, hey free land.
So, it's 60 years later, and someone stumbled on the wizards' lair, a sprawling dungeon they've been building for the last 50 years... inside Kingdom B's territory.
This is an issue because Kingdom B doesn't want to allow a heap of Kingdom A soldiers to come into their land to assault the dungeon, and doesn't really want to annoy some evil wizards by sending their own soldiers.
So the dungeon is opened up to adventurers, like the PCs. The idea is that the adventures will vary in focus between simple dungeon-crawling through a maze built by multiple mad wizards who don't all get on perfectly well, and some degree of political intrigue, as multiple kingdoms/other groups have differing attitudes and interests in regards to the mad wizards and their abominable magics (ranging from "BURN IT ALL" to "we want to use it for ourselves").
