"Huh? Is it because of iron there or?" It's not often I heard of thematic names. Everfree, for example meant wild. Appleossa, some town I was vaguely familiar with because of one of customers, was related on apples. Canterlot was related to castles, as I heard from history lessons before being trapped in the bag (Thank Celestia for a hut, since if not for that, I'd die). And then Cloudsdale was related to clouds.
