Heller's POV:
Everyone was at a loss regarding the 'house'.
Undoubtedly, it was alive. The rhythmic pulsations of the flesh were like a person's breathing, regular and methodical.
Investigators extracted samples of the flesh for analysis, and unsurprisingly, it was Yarin. He seemed unable to perceive any external stimuli, incapable of communication, not expanding outward, and tightly clutching the framework of the back room to transform himself into a house.
The werewolf grandmaster's investigation indicated that this was a form of power running wild. Yarin's instincts were expanding himself at any cost, turning the entire house into his nourishment.
