cool I don't mind waiting but the sooner the better. 
Also there probably wont be enough wings to go around how will we handle that here?
Yeah, I've been thinking about those elystra or elytra (aka wings), whatever they're called.
I
probably won't have to add borders in the end since there isn't as much data in the end so the map size isn't as much of an issue. So even though end cities are rare, and not all of them have the ship (where the wings are) perhaps we can just let anyone who wants to take the time and go the large distance to find them be allowed to keep them.
It's kind of like how jungle temples are rare, and whoever had found them could keep the chiseled bricks (before they could be crafted)
Not sure. Opinions or suggestions?
