An ancient land with a wonderous albeit forgotten past. Immortal spirits and other ethereal beings are common here, with giants and megafauna, ogres, dragons, and fey being present though less common.
The Esu are native to Relm with some bloodlines populating certain regions more heavily than others. The civilization is in a state of both early feudal themes and advanced technology through various magics and preternatural energies manipulated by the Esu themselves.
