As one of the investigators hired to take a look at the Harmony Opera House, Gazlit and his team were confronted by Walden Stein. Here is where they learned of the ongoing within the opera house that needed a rather unique touch.
As one of the investigators, he and Fremrock checked out the mannequin room where Fremrock beheaded some of the mannequins. Further down, Gazlit later checked out the dressing rooms with Professor Mittens. They came to the conclusion that there really wasn't anything out of the ordinary within these areas. It was deiced that as the others went for mexican food, he and Fremrock would hide out on the rooftop.
Once up top they were able to watch the workers go about their normal duties and didn't catch anything strange with their movements. When the others returned, the haunts began. Gazlit was more fortunate than the others during the encounter with Valora. However, after her banishment, a new figure took her place holding onto her severed head. The individual thanked them for pointing out the failure of their subordinate and disappeared. Thus concluding the investigation of the opera house.
