Well it's nothing much actually~ The chair has a bunch of crystals on the bottom side. Those crystals hold the float magic that keeps it floating. As such the hovering cant be broken unless the sturdy crystals are broken to small pieces or removed. The only broken part is the small engine that was supposed to make it move. Back, forth, left or right and even strife. If you want you can try to fix the engine. I leave you the choice of if you wana and if you will manage to repair it to you. It could be something as simple as some water entering the engine or something. You decide :3
