Cassandra Avin

Cassandra Avin is a human paladin of Helm and one of the few survivors of the Helm's Keep Insurgence. She stayed on the surface of Ilrea for a while after the insurgence, before leaving in search of Hyde Vermillion. She fell into the Underdark in the same dungeon that had trapped Hyde, and found him in Helmsgate a few days later.

She then moved to Cocytus on Figura 24 Y971 so that she could help Tartarus in their mission against Valna.
