Pieces of a Fallen Star (Pokemon OC Fanfic)

Three kids in over their heads. All Sun knows is this summer is going to be the best summer of his life. After all, he and his best friends, laid-back Hau and hot-headed Mizuki, are finally going to take on Alola's island challenge. They’re determined to succeed even in spite of all the obstacles life has to throw at them: unruly starters, cultural tensions, enraged guardians, a sinister cult. One Pokémon, and their unwilling pawn. All Lillie wants is to return the odd little Pokémon she's rescued to their true home beyond the stars. What she doesn't know is that Nebby doesn't want to be returned - and they aren't as benign as she thinks they are. They aren't benign at all, and they aren't above using any tools necessary to carve their path of destruction through Alola. Even a quartet of innocent children. One fateful evening, the two parties collide - and Alola will never be the same. Pieces of a Fallen Star is a character-focused AU of the Pokemon Sun and Moon games with heavy divergence. While it is not grimdark, but it does have its fair share of darker themes and plot points, including but not limited to human and Pokemon death, child abuse, and religious trauma.
