Willy not being War Hammer is definitely a possibility. He mentioned that only a select few knew its holder, and wouldn't everyone just assume he had it since he was the head of the family? I don't think being the head of the Tyburs necessarily means the person has to inherit it either.

The real holder could've either told Willy about the Great Titan War real events, or was able to show him the memories somehow.
