Acolyte Callonia

 is an Imperial mage and a member of the Mythic Dawn, who secretly operated within the ranks of House Redoran during the Oblivion Crisis.

Background
Born in Bruma, Callonia began expressing interest in Mehrunes Dagon's cults upon reading the Mythic Dawn Commentaries. She was introduced to a coven of Mythic Dawn cultists at the age of nineteen, and progressed to the rank of Acolyte since.

During her time in the Mythic Dawn, Callonia came to possess Xefhedle's Locket.

Third Era
Callonia was sent to Morrowind in 3E 433, tasked with infiltrating House Redoran in order to weaken one of the greatest opponents and let the Daedric Forces of Destruction invade the province.

When she is encountered by Urjorahn and the rest of the group, she is disguised as Master Hlormaren Redoran's second-in-command, and helps the warriors close Oblivion Gates across Vvardenfell. However, she then makes an unsuccessful assassination attempt on Hlormaren, revealing herself to be a Mythic Dawn agent. She helps summon the Great Gate at Balmora, but is killed shortly thereafter.
