"Well, look who it is. Thanks for taking out those deserters for me, Tyr. Have you come to serve the Emperor once more?"
―Legate Cassia to Tyr[src]

Legate Cassia was an Imperial Legate during the Great War between the Third Aldmeri Dominion and the Third Empire.[1] She joined the Forgotten Hero during his quest to aid the Empire, after the Hero had taken down a group of Imperial Deserters. With the company of the Hero and his followers, they went to the Imperial City, posing as Gladiators, to find out the source of Naarifin's power.[2] During the Battle of the Red Ring, Cassia commanded a part of the Imperial forces.[3]
