Shadow Over Volfsten
This island is home to the Academium Arcaneum, the greatest university for the arcane arts in the whole of Baltaria. The Great Library of Imperium is the greatest wealth of knowledge the world has ever known. Imperium is a place for magic-users to study, practice, and hone their talents free of societal restrictions.
The masters of Imperium are the High Council, a group composed exclusively of tiefling arch-wizards.
