Yes. She teaches Conjuration and Mysticism and Destruction at the Mage Guild. You think she might be involved in the Gateway haunting? Well. I suppose it's possible. Uleni Heleran has a mischievous personality, and she has some sort of bad feeling for Angaredhel and the Gateway Inn. I also noticed that Uleni Heleran has been magically transporting into Wolverine Hall quite a bit lately. Maybe she's using a Mark and Recall spell sequence or a Divine Intervention.
