To receive training from her, the Hero needs to finish the quests Breaking the Siege of Kvatch and The Battle for Castle Kvatch, and inquire about training from a previous Restoration trainer. This adds the quest Restoration Training, which simply directs to Oleta. She can be found at the Chapel of Akatosh inside the city, but she moves to the refugee camp south of the city after the Chapel is secure. However, if Knights of the Nine has been completed, other replacement Restoration trainers appear, none of which refer to Oleta for Master-level training in that skill.
