Mount Palmerston
From The Fifth City Wiki
A large volcano in the unterzee, to the east of Codex. The devils on the wrong side of the revolution have taken shelter here, under the name "The Brimstone Convention". There is also human settlement, the remains of several other human settlements, and a large soul trade going on. The humans do not seem to mind the devils, as they keep to themselves.
The wistfull Devilless may be encountered here.
