Vatasha Trenelle is a novice battlemage who entered the Battlespire shortly before the Apprentice did, and was trapped during the Daedric invasion. She leaves them helpful letters and items, as the Apprentice follows in her footsteps through the chaos. She is found in Dagon's Hunting Lodge, held prisoner by the Daedra Prince Mehrunes Dagon in his inner sanctum behind a Hekem Sigil of Warding. She is found naked hanging from the ceiling, wrists tied with rope and appears to be unconscious or in a deep sleep.
- Vatasha Trenelle only appears if the Apprentice is male. If they are female, she will be replaced by Josian Kaid.
