Princes of the Apocalypse
None who live in Oakhurst know much about this place. Rumors claim it was once used by an ancient cult, though none alive remember this cults named. A disaster of some sort caused the Citadel to fall into the ravine near Oakhurst.
The cataclysm that killed the cult off also sunk the Citadel at the same time. Because of residual enchantments, much of the citadel structure survived its descent into the ravine and lake.
At some point, it acquired its title of “drowned”. Some believe the place still haunted. Others claim its merely a squatting place for bandits , its contents long been scavenged by grave-robbers and the adventuring type.
