Ooooh ... this one looks fun. Now I have to come up with a fun idea that would also fit in with my campaign setting ... hmmm ... giant blastocyst shaped air-ship? Meh ... can't let players get air-ships, they always go ape-guano over the setting if they get something like that. Crab walkers seem to have been done extensively already ... but maybe a small magickal university built on top of a giant gong supported by four undead elephants ... nope, been done.

Maybe a settlement built on top of a giant mechanickal centipede ... a walking, huffing, puffing ore-refiner or something like that ... hmmm
