Do it, DO IT NOAAWW!!!!!1!1111!!
Great idea, was going to ask if there was something I was missing, please add owner. Great mod by the way.

Yes, good idea, but hard to implement, it will take a long time.

It would be a good idea if by completing the quest.... the entire castle gets destroyed. This would give you the ability to rebuild the city from the ground up as a player. the player should have to find new npc's around the world of skyrim to repopulate and rebuild the city and castle. I find too many mods with fully furnished houses/castles that hand you every thing without a second thought on earning and questing for it. More over, to many mods let you finish a quest and already have everything owned in a house at the end. This erks me. Yet I never see any mod where you finish all the quests and then have to rebuild the place that was destroyed and or repopulate the place that was destroyed for the citizens.

I like the idea of the castle being in the sky, that IS the whole point of this mod...

Though this idea would be very to extremely difficult to implement, it would be nice if the castle would be actively drifting around the map at maybe around a meter per in game hour. This might make it difficult to get to it though, and designing a moving fast travel marker would also be difficult to implement. Seeing the castle still be fully funtional and move at the same time would be a truly majestic/epic sight. (At least from my perspective) I don't know if this has been suggested or not, I just thought I'd put it out there.

If this were to work out, how wold we find it the first time? We would have to look around skyrim for hours trying to find this castle if it actively moves around the map.
