Long, long millennia ago, during her self-imposed exile into the Catacombs of Delsyis, the FirstBorn Daughter of the Primal Elements learned of the existence of a Keeper.
With Aunsa's help, Dellasseea N'Syis traveled incognito to an unknown world in order to find and reclaim that which had been raped away. But, once she looked upon the Keeper--- she could not bring herself to be the cause of his demise. Instead, as Time passed, she found what otherwise may never have been known to her--- Love.
With the eventual passage of Time, and an innocent slip of Thought, the Old One's secret world was discovered. Once realized, a long proscribed act was invoked. The FirstBorn Daughter's Crystalline heart was bound to that of the Keeper's Human Hybrid heart in order to protect both from Annessau's imperishable wrath.
With another, even greater passage of Time, and a dark Bargain struck, there manifested (almost unknowingly) an interruption of Eternity. Protocols were by-passed. Gateways were breached, and Dimensional shifts maneuvered; transgressed. And while the embers of the devastation that followed still smoldered, and Dellasseea N'Syis made to think him dead--- the Keeper traveled to a long forbidden world, and transmutated himself willingly through Time. All done--with full intent--to find that which the Old One bound to his heart, and bring back to their beloved EeDellon; the origins of Humanity.
