Well, if you look at the Ministry of Truth from Morrowind or even Umbriel from the Elder Scrolls novels by Gregory Keyes, it would be entirely feasible to have a floating landmass of some sort. If such a landmass were to exist, it would most likely be powered by some arcane power or artifact and may have never been seen by the people of Tamriel due to it hiding in clouds or having some kind of invisibility field. It'd actually be pretty interesting, I reckon.

As for your idea of humanod rabbits, it's not as absurd as you would think. There's a game called Overgrowth (official site here, Wikipedia here) that features anthropomorphic rabbits as a race (as well as wolves, dogs, cats and rats).
