The Legend of Nirn: Oblivion's Call - Chapter 1: A lust for closure
Avernus is first seen in this chapter fleeing from a small group of ghosts, with his companion, Kairi. The two of them trap themselves inside some sort of chamber, where they have no visible means of escape. Avernus immediately begins looking for some semblance of a way out and notices that the ceiling above their heads is cracked.

Before he can respond, the ceiling is destroyed and a murder of crows dies down into the chamber, scooping the two mer up and flying off with them.

The two of them are later seen in Agatha's hut, when Jude wakes up from being grabbed by the swarm. They follow Agatha out as she begins her journey to Castle Volkihar.
