Biography
Sejanus was tasked with making interrogations of subjects. He threatened them with death unless they recanted. After the death of Pepin VI, Sejanus arrested his wife, Berengaria. As he escorted her to the jails, he accepted a bribe from Childeric, allowing him to speak with his mother.

As part of Pepin VII's initiation, Sejanus raided the king’s quarters and fired a gun at him as a test of his immortality. Pepin survived as it fired blanks.

After Pepin's abdication, Sejanus pledged allegiance to Frobisher, the new god. (BFA: The Holy Terror)
