Ophiuchus

Hidden upon the Astral Plane is the Sphere of Ophiuchus, long rumoured, but lost for ages. This legendary thirteenth astrophere was discovered after an attempt by High Prophet Ghani n'Rotri to empower himself and become the Avatar of the Soulless God Kethuru. He built the Orrery upon Ophiuchus to focus and collect power from the twelve other astrospheres and to pierce into the Realm of Pandaemonium, paving the way for him to hijack the Ascension that occured 498 years after the Coming of Estarra. Ghani suffered an unfortunate fate after his defeat by Veyils, now known as Deichtine, who rescued the Staff of Ascension from the usurper and locked Kethuru away once more. Now, the Ophiuchian Orrery lies open to all, and its many mysteries remain for those whose curiosity drives them to seek, perhaps to their doom.
