The man with the probe
1) Not sure, but it's common mythology taught by some of the deities, so it's there.
2) Rivensblight, as RA mentioned, was a city once mostly for elves, but it's a fallen and corrupted city. Grey Elves could come from anywhere, or you could make up your own snooty city.
3) I could Giants by the tower (I'd expect frost by either air or water more than earth, but that's minor) and there are several mountain ranges around that might have giants.
Keep in mind, no one's been very close to any of the towers.
