Seven Keys

Marie Kessler gave a key to Nick Burkhardt in without explaining its purpose before she died. Kelly Burkhardt told Nick its origins. She revealed that the key is one of seven that belonged to seven knights who were ancestors to the Grimms. The knights worked for the seven families in the twelfth century. After sacking Constantinople in the Fourth Crusade, they took a treasure back, made a map on the seven keys, and each took a key. The keys, when put together, reveal the location of a treasure. The treasure is supposed to be an artifact so powerful that, if held by the seven royal families, it would allow them to rule the world. A second key was revealed in.
