A living house is exactly what it sounds like. They are carnivorous, with the power to lure humans inside and devour them. Gabriel “Bones” Boone discovered one had eaten the son of his client, Rosalia Rivero. He and Chevalier discovered the house, but Bones was lured inside by the smell of baking. After the house manifested a tongue coming down a third-story attic that shouldn’t exist on a two-story house, the mages fought it back with the help of Fatou.
