As one of the investigators, Blaise was hired to investigate an opera house. Despite the things she and the others have been through, Blaise was always a skeptic of the supernatural.
Upon arriving to the Harmony Opera House house she made "eye" contact with The Plague Doctor who was concealed with a raven's mask. She could feel a shutter within her spine, but didn't think much of it at the time. The group proceeded with their initial investigation after speaking with Walden Stein, Diana Voxville, and one of the singers Sasha.
Blaise, not wanting to believe that a ghost could be behind it all, assisted in speaking with the construction workers that were present in the lobby. She learned that there were a few construction workers who died by various means that appeared to be explainable accidents.
She and the others regrouped together where they eventually were called to the ticket booth to begin their investigation later in the night. She adhered to Fremrock's request of something called Mexican food as the group had split up into two for the time being.
Upon their return after night had fallen, Blaise and the others continued their investigation. Things escalated when haunting activities began within the opera house. However, with her experiences, Blaise shrugged most of it off to a reasonable and logical explanation of things. When the auditorium doors unlocked and the group proceeded inside, they were face to face with the entity known as Valora. A fight began with the being which resulted in her being banished. They prepared for the sudden return but was met with an individual in plated armor holding onto the head of Valora.
They learned that Valora was Sasha the singer they had spoken to earlier. Sasha appeared to be some sort of pawn for the individual now holding onto her head. Still not fully convinced of paranormal activity, she and the others turned in for the night to meet with Walden the next day.
