Just recently I had started getting a lot more into Warhammer beyond just skaven stuff thanks to Total Warhammer 3 which led me down a whole rabbit hole of reading all the horror-related lore and associated media I could find.
While going through it all, it had led me down the road of roleplaying a witch hunter in Dwarf Fortress, hunting vampires and were-beasts, that sorta thing.
But while I had done this, I noticed that a lot of the current ingame lairs for creatures that use them are... pretty limited.
Sure shrines and burrows of night creatures specifically can be cool, as well as mazes, what with all the loot and corpses of previous adventurers strewn about, but reading about geist-haunted lairs, norscan folk keeping werekin locked away, castle Drachenfels, creatures of Nurgle hiding away deep within the sewers of towns and so on made me think of how much more potential megabeasts and night creatures could have in terms of atmosphere and gameplay.
- Haunted/abandoned mansions
- small huts in the wilderness
- fallen towns/cities
- towns/cities with their own specialized areas for megabeast worship
- Wandering the streets of Towns/cities under certain conditions like weather, time of day, month, week, etc
- Graveyards with maze-like catacombs, crypts, and tombs underneath them
- Ruined castles
- Old farmsteads littered with dead livestock
- Ritual sites
Just imagine it, you're either a hardened warrior or a lowly peasant, being hunted down in the abandoned ruins of an old town by the dragon that has now made it's home there, or maybe you set up camp at an old house only to find a horde of bogeymen thriving within the basement, or better yet you go full on Castlevania on a vampire who resides within one of the many haunted mansions across the land.
So many possibilities that I feel would really add to both the horror and atmosphere of pretty much any creature that makes use of lairs.
Heck, why limit it to creatures? Civilizations, depending on how recent the battle was and the morals of said civ, bodies could riddle the alleyways or be thrown in newly constructed corpse holes outside city walls or just simply dumped into the sewers.
Haunted mansions could be temporarily turned into outposts only to go horribly wrong and everyone there murdering each other because, you know, it's haunted.
Again, SO many possibilities that could add more than enough flavor to what are essentially the bosses of this game.
