Horrendous Habitats

From [Ironstorm Mountain] Introduction:

The Horrendous Habitats series features ready-to-use lairs and hideaways to be integrated easily into your game. The idea is to feature a complete and detailed “home” for your chief antagonist, one worthy of striking fear and loathing into the heart of the players upon entering it.

Our goal with this series is to furnish DMs with a set of easily adaptable and usable locations that can be used to enhance your already existing adventures, and which serve as an inspiration or standing plot hook for a longer campaign.
