Rexus (Skyrim)

Rexus is the Imperial bodyguard of Amaund Mottiere who you meet during the Dark Brotherhood questline. He can be found in Volunruud at first and later in the Inn at Whiterun.

The only glitch yet reported is that as soon you enter Volunruud, Rexus will become your hostile and will start attacking you. I recommend you to make a save file before you enter Volunruud.
