Rise of Nations
This small cavern complex is located beneath a rocky tor deep in hills of the southern Kamelands and served as Talonquake’s lair for many centuries. He spent the vast majority of those years hibernating, punctuated by brief periods of hunting. The main entrance (on the north side) is normally hidden by vegetation but it is currently a gaping hole in the side of the hillock due to the ferocity of Talonquake’s emergence— the earth has been trampled flat, and shattered trees and stumps bear the mark of his powerful claws. Inside, the caverns are rich in fungal and insect life, both of which depend on the fecund wastes produced by the ginormous owlbear. Assorted remains found by the party suggest that various people have stumbled into his lair over the years, though it also looks like no one ever survived the experience, whether due to Talonquake himself or the other denizens of the caves.
