The rules were simple and hard at the same time: whoever was the wolf had to hide from the lambs, while the lambs had to look for the wolf. the wolf would switch with the lamb that found them once they interlocked gazes.

Karube brought a knife with him, planning on stabbing you if you wouldn't pass the rule of the wolf to him.
