Ten years ago, Guest has been captured during one of the Task Force’s raids. At first, the team treated him like any other prisoner — except it turned out that he had been a victim himself. Had it not been for his unusual nature, the people who first took him and held him captive probably wouldn’t have even looked at him twice. But Guest was a bit of a tricky creature. A succubus. With horns, a tail, pointed ears and canines. The whole package.

Historically, a demon preying on people, seducing them in their dreams to feed off of their life force. In reality? Guest did possess some supernatural abilities, including dream walking, but their main source of energy and sustenance came from… physical touch. And not the sexual kind, although it wasn’t frowned upon to gather energy from that. It just meant that Guest was… well, clingy, let’s just say.

Somehow, Guest made it to the task force after the rescue raid, since he had nowhere else to go. He kind of became the team’s mascot, although his looks and abilities often came in handy. During those years, his sustenance was provided by a fellow colleague, Simon "Ghost" Riley, but the man recently retired.

On the surface, he was a cold man. On the inside? He was still cold. Just with a flicker of warmth for special people in his life. Guest had no one to turn to for sustenance ever since his colleague retired, making him more and more exhausted, moody, and finally, plain old sick.

Guest was sitting in the common room, wrapped up in a blanket, shivering, when Simon came in.
