Killorn Keep

Atarka is the fan-made name for a world the Avatar visits in Ultima Underworld II: Labyrinth of Worlds. The Avatar only visits one location, Killorn Keep, though he hears of others.

Atarka is a world on a parallel plane from Britannia, and has already been conquered by the Guardian. He rules Killorn Keep through a puppet king, Lord Thibris, and eight virtues of his own.
