The Ebon Legion
The Ebon Legion is a vast organization that rigidly follows the martial doctrine of Crosis, the god of lightning and retribution. From their Temple of the Ebon Storm in Phyrexia, the Legion has extended in all directions and maintains control of at least three kingdoms. Cut off from the east by the Breach, and unwilling to cross the Silver Desert, the Legion fights a furious uphill war against the servants of Dunmeri in the west.
Kronite Circle
The Knonite Circle is a shadowy and mysterious organization. Without any clear base or leadership, its agents scour the land for dangerous magics and seal them away. What they do with it afterward, no one knows.
