Aethorin was a half-elven priest who lived in the small port town of Manatheran before the eruption of Mount Illian. He was visited in a dreamvision by Ennis Arden and advised on how to create the pillar that now stands to defend the city.
After using his magics to create the pillar he joined with it during a ritual peformed at noon. Through his sacrifice the Pillar of Aethorin was created and is a beacon of light and hope against the darkness that threatens to swallow the island.
