Tome of Solomon
The Tome of Solomon is a mystical artifact which contains the collected knowledge of the powerful Demonologist King Solomon. The book could only be unlocked by using the Key of Solomon which 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 for a short time. In that very short period, Ornais affected the release of all trapped members of the Order 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.
