suggestion Less random drifters, instead make cave colonies

[Rendrassa]

(Kinda spoiler warning for lore.)

What lore I've come across imply that the drifters are corrupted humans who have been warped by the temporal shifts. So, what if there were cave colonies that the drifters spawned around? Colonies might have other, less hostile mobs inside the low tunnels, with possibly loot or story fragments.
