Adventures in Anterra
Keep of the Boregan
The Boregan were sorcerers from times past whose center of power was East of Paropolis and West of Humbrell near the Great Trade Way. They were also associated with a magical plague called the Endarin Plague.
The keep itself is located in the Vale of the Forest Drake. There are 3 stories underground, with the entrance to the top levels above ground being ruined and in danger of collapse, but the levels themselves have been unexplored and unopened for centuries (cue spooky music). The lowest level has 2 pools that were full of slimy, nasty water full of undead fish, and a magical fungus that can be used to treat the plague. The river in the valley floods and washes mud and water into the lower levels of the keep, making portions of it muddy and incredibly slick (the stairs in particular).
