Killorn Keep

Atarka is the non-canonical name for a world the Avatar visits in Ultima Underworld II: Labyrinth of Worlds.

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.

Atarka's name was originally generated by Shadow of Light Dragon for her Ultima fanfiction "The Black Ankh", and the name has since been widely accepted by fans of the Ultima series.

Killorn Keep
Killorn Keep is, where Lord Thibris presides. It is a castle that flies 1257 feet above the great Northern Wasteland of Atarka. The Avatar is told that it is used to intimidate the nomadic, babarian people of the desert. The Guardian's magic holds the keep in the air, through it can be disrupted, resulting in the keep crashing. Killorn Keep is not the central power of its world, as many see it as a backwater and consider being trasferred there as some kind of penalty.

Killorn Keep was used as a staging area for inter-dimensional invasions.
