One of the ways the Celestine of Kemet acended was drinking the blood of the dream sphinx known as “Watcher of the Horizon”. From the Blood of the Dream-Sphinx, they all shared in a greater consciousness, and were able to combine their powers as though they were one in that moment. Some were driven mad, many died, but those that lived shared a shining consciousness with a portion of one of the Olde Ones – the source of the dream-sphinx they had captured.
One of the interesting qualities of celestine blood is that it carries the genetic markers of any blood added to it. If a weapon is attuned to a particular bloodline, a celestine can drink or inject 1 oz. of blood from a source and it becomes part of their own, thereby being able to wield the weapon. This can be done with the blood of any creature, though costs 1 Essence permanently to activate this capability in their own body.
