Who is Noir?

The loud crash from the room next door startled everyone, snapping Tygr out of his memories. Immediately, all of them rushed to the next room.

Solis was on the floor, having knocked over the cabinet near the bed. Thankfully, he had already cleaned up Noir and put him on the bed by the time the memories of Tygr infiltrated his brain without a single warning. Solis's instinct had been to move away from Noir in case he ended up hurting his beloved fiancé inadvertently, so he had backed away quickly. Unfortunately, he hadn't been steady on his feet at all, and thus had ended up crashing into the cabinet.

So now Solis was on the floor, with books and broken things strewn all around him. He was doubled over in pain, clutching at his head desperately and unable to move or speak at all. His beautiful face was twisted in agony.
