The Wolf House is a place where Roman demigods start their journey. It is there where Lupa judges whether the demigods left there are worthy enough. If so, she takes them into the Roman Camp Half-Blood. The House was built by Jack London, a son of Mercury. It is where he found out he was a demigod. London thought that he could live in it, but it burned in a fire a week before he and his wife were supposed to be moved in. It is described to look like what a millionaire lumberjack would live in.
