History & Background (Dossier)

In addition to the City of Sonthert, the other major settlement on Sonthert is Ar.

Sonthert is interdicted both to protect its human population from interference, and to protect the rest of the Imperium from the megalomaniac "Emperor of All Things" and his armored knights, who have declared their intent to conquer the universe, starting with anyone foolish enough to land on Sonthert.
