Agrius was an Imperial bandit. His corpse can be found in Halldir's Cairn, right next to Raen and Vidgrod, along with his journal.


According to his journal, he and his cohorts were members of the Knifepoint Gang but were expelled for unknown reasons. The three were hiding out at Halldir's Cairn, but were then held there by Halldir, who forced Agrius and the others to sacrifice themselves for his magic.
