fine ill make a super fantastic story to explain it.... ahem

    a long time ago there was a world wraped around this ours like a big present exept there were people on top living and thriving. except there was an evil king who would asign random endles tasks to unfortunate people. one of these tasks was rock turner over who had to turn every rock in the world over, the poor boy named phil did this for many years until he was 32.. no 34 and turned over a rock only to find a big shiny red button. being a mid-evil  era civilization everything was of course covered in mud, that was jims job. so phil pressed the button and BOOM! the world explodes except for one village that had a really unnecisarilly big wall (which was franks doings) so it survived the big explosion. the people used the stone that was left from the really really big wall to build a stair case down to earth and founded the first town there.

Wait so you are saying that mystical powers make sence when a foundation for a town in the sky does not? put some legend behind it like maybe some really strong wizard decided to punish a town by sending it into the sky of something?

sorry i saw it was 2 years old after i replied, but would it be possible*Question mark*
