Falling Star - per aspera ad astra // A Supernatural Fanfiction

[S14 Spoilers!] Since when do demons move through the country in packs? Why are stars suddenly disappearing from the sky? Who is the strange creature, following them and turning everything in their way into rubble and ashes? What initially started with a relatively regular case, to which Sam, Dean, Castiel and Jack were called, ends up entrapping "Team Free Will 2.0" in a sprawling, seemingly inescapable spider web, made up of dozens of interwoven secrets and unsolved questions to which nobody appears to have any answer. What is Jack hiding about Mary's death? And who is the puzzling girl with the unpredictable abilities who evidently appeared out of nowhere and might she be the one, despite her lack of memory, holding the answers to the numerous questions in the end? Is she also hiding something? A hallucinated savior perhaps, who might not be as unfamiliar as he pretends to be? Concealed enemies, apparent friends and new hopes pose a vast challenge to the Winchesters and their friends, maybe even making them question their initial moral understanding.
