Key of Solomon
The Key of Solomon is a mystical artifact whose sole purpose was to unlock the mythical Tome of Solomon. The Key was hidden inside a false cavity in a medieval castle located on the Island of Crete.
The elaborate plan involved several members of the Blackened Denarius, and allowed Ornias control of the Tome just long enough to free all members of the order sealed away to be freed.
The Key and the Tome were recovered and given back into the care of Thomas, who hid them away, before disappearing himself.
