The Second Empire made some advances into the periphery of Black Marsh, but they didn't stay long. Arx Corinium, once an Imperial fort, is now occupied by denizens of the deep swamp—and even stranger things.

Arx Corinium

Arx Corinium is a group dungeon found in western Shadowfen. While previously constructed and held by the Imperials, the fort has fallen into disrepair and is overrun with Lamias. A group of nereids now occupy the flooded fort and focus on restoring balance to the land. Rumors say the fort is home to a great source of power, although it is perverse, corrupted. You can learn about its location from Mindil the Untested in Marbruk, Abzag the Monster in Shornhelm, or Maela the Crone in Stormhaven.

Its dungeon sets are Lamia's Song, Medusa, and Undaunted Infiltrator.
