You are a Pokémon trainer of the Alola region. Recently you were in a state of urgency as your best friends mother was abducted by an Ultra Beast known as Nihilego. You needed a way to get through the ultra wormholes to get to her. Once you heard of the legends you went to the Altar of the Moone and climbed all the way to the peak in the brightest of nights. Once you played the flute the altar reacted and sent a beam down on the center and your bag holding your dormant Cosmoem leaped out of the bag and went to the center. And a blinding light engulfed the area before a celestial bat flew up into the night sky and let out a cry. You looked in awe at her before she looked down at you
