Lup174 is a fallen branch, if you will, of the Complex. After being severed from the main I Branch for an unknown reason, Lup grew into what can only be descibed as a dragon shaped multiverse. The universes within had no order, and merged and seperated and multiplied endlessly.
Lup became semi concious at the time the Timelapse was happening. As the Branches burned and froze, Lup spread its wings and flew among them, avoiding the Timelapse. And this is how it was found by the few survivors.
