I'm really interested in the story of how Jack lost his wings.
The story my brain is conjured up:
I'm thinking something along the lines of he and Mark were close friend who live in the same village that floats above the clouds. They were exploring in some sort of forbidden location and stumbled upon something old and powerful. It cursed Mark and Jack, splitting their personalities into their "good" and "bad" sides. Scared and confused, Mark flu back to the village, leaving Jack behind.
The creature trapped Jack by making escape nearly impossible and was forced to fight for his life and in the battle, had his wings ripped off his back but somehow managed to fend off the creature. Though alive, Jack finds himself to be on his own, forever unable to go home to his village in the sky. As time passes on, he finds himself adjusting to the world below he knew so little about. Though much time has passed, Jack had this voice stuck in his head that convinced him he couldn't ever forgive Mark for abandoning him that day.
When Mark arrives back at the village, he is confronted and while drowning in fear and worry, Mark's newly-prominent darker side convinced him to put all the blame of their forbidden excursion solely on Jack. When Jack finally makes it back to the village, he is confronted and found guilty through witness (Mark) for breaking one of the oldest laws known. He is then beaten, his wings cut off, and is exiled from the village. Jack is forced to make it on his own in a world he has never encountered before, and while influenced by this alluring voice, swears Mark will pay for being the backstabbing "friend" he is.
But in the end:
Jack eventually seeks help for this nagging voice. He attempts to have it removed via magic, but in doing so he ended up creating Anti. Hey, he out of Jack's head, right?
This is as far as my little brain can take me. If anyone want's to elaborate, extend, improve, spin-off, adjust, etc. go for it.
I would really like to know what your take on it all was when you were making this. 😅
