Creation
There is no universal comprehensive theory for the creation of the universe, though it is agreed that the first being to exist, Ai-An, must have created the universe by initiating the worldsong. The primordial world loved its creator intensely, but Ai-An, being the Original Being, was unable to feel similarly. This prompted them to create themself a mother, initiating the event called Paradox Supreme, which created infinite world-iterations.
