On the ancient realm of Adena, the only constant is the chaos of war. The planetlike Adena has two "moons" which are in truth remnants, one home to demons of wrath, the other to angels of zeal. Their unending battles mean the people of Adena never know peace.
The order-loving realmlord of Adena strives to contain the chaos, but the war between angels and demons threatens to overtake Adena's purpose. A monastic order devoted to a mysterious entity with two faces, one angelic and one demonic, may hold the key to the realm's restoration.
