3.5 Flying Castle?

[casper]

Who's going to create that castle? If he is an epic spellcaster, have epic spellcaster among his friends or have enough money to hire one, he can research custom epic spell, which would make castle fly, create a cloud to carry it or anything like that. "Fly" isn't in list of epic spell seeds, but I don't think that anyone would disagree, that such a spell can exist and its Spellcraft DC wouldn't be too high even for low-level wisard, especially if he would make it a ritual.
