Eons ago, the In-Betweener, the balance between the opposing entities Lord Chaos and Master Order, created a dimension to serve as a place of personal reflection; but the realm - which would become known as the Ankh or 13th Dimension - grew a life of its own. A race of beings obsessed with order and chaos developed there, worshiping the In-Betweener as "Ankh," their all creator. From the carved stone of their world and the spilled blood of the lamb, these beings, the Brotherhood of the Ankh, created the Zodiac Key, serving as the mystic value to the Ankh's power and striking balance between chaos and order. In the 4th generation of their "Century of the Leopard," the Brotherhood's Lawholder discovered as their world calmed their world was weakening, and the Brotherhood's life energies began fading.
