Perinian Depths

Description
The Perinian Depths is a dungeon in the Sosaria of Ultima III, located north-east of Britain.

The dungeon is often one of the first to be explored, as it is the easiest dungeon to acquire the Mark of Kings. The Mark of Kings can be found on levels 1 and 8, and the Mark of Fire, which would make lava harmless, can be found on level 8.
