The Hundredth Time

You were once a deity of Light, the Dawncaller, the one who forced the star to rise over the horizon. You had a world to build. You also had a rival, the deity of Darkness, the Duskbringer, who, each night, made your efforts for naught. Your rivalry led to a love, which went far above your deific domain. You were together for what seemed like eternity. Until the end of the Age of Gods. By the time the world was complete, your kind were forced to make a choice. Dissolve into the Cosmos to see what the mortals make of it, or join them with one boon bestowed upon you for your work. The choice was easy. Yourself and the Duskbringer both wished to live a hundred mortal lives together. This one is your last.
