Oghma is a secluded island some distance south from the main continent. At one point, it was part of the mainland, but was severed off during The Godswar. Many scholars and priests fled to this area for sanctuary, taking all knowledge of the previous world with them.
It was this island each of you came to call home. Trained in the ways of sorcery and combat, the Lorekeepers kept you safeguarded until the fated day came when you would leave, venturing forth to restore the old Gods to their former power.
