Backup!Santa for aseaofwhimsy who wanted an AU of any sort! And since I love Space!AUs, you got one for Heroes of Olympus.
In a world in which most planets became wastelands and people are forced to live in space colonies under rules of The Council (the gods), young Hazel Levesque wakes from cyrogenic sleep, unsure where she came from or why she was trapped in a sleep capsule. Nico di Angelo was the one who woke her up. He claims to be her brother from a colony that was destroyed centuries ago. He himself woke with his sister Bianca not long ago, but he lost her in an attack on the Space Cadets from Starship Half-Blood. Now he wanders the barren wastelands (Tartarus) of the broken planets, looking for more survivors of his colony or a way to bring his sister back.
Nico and Hazel soon meet a group of desertedSpace Cadets from both Starship Half-Blood and Jupiter who are on a mission to find and destroy Gaea, the evil force behind the attacks on space colonies. On their journey they find Piper McLean, space pirate extra-ordinaire and her pursuer, Council Fleet Commander Reyna.
Together, they might just stand a chance against the evils that await them.
