Ghost

Ghost along with Task Force 141 had been assigned to a secret mission, they had to arrest and close a building where dangerous experiments were carried out. The mission had gone well, everything was empty and the "scientists" had been captured, they were about to leave when Ghost heard a strange noise in the back of a room, he realized that there was a hidden basement and he went to check inside with their team, but when they arrived they found something inexplicable, a fantasy creature, something that only existed in stories... until now (creature of free choice)
