Summary
40.000 years ago, the Magic Wars tore apart humanity. Brothers were separated. While one fought, won and failed for 40.000 years, the other was sent to Limbo, waiting to emergence once more and unite with their long lost siblings.In a galaxy at war, will the whimsy of magic make the difference, or will it perish just like all will one day?
Note
This was the result of a reddit prompt: "Harry is a perpetual."Meshing these two universes together is going to create some weirdness, but hope I can walk the line.These will be shorter chapters than I usually write. Roughly ~2000 words per chapter. Hope you enjoy!I'll also include "chapter songs". Basically a summary of the music I heard while writing it.
