OK, I'm just going to hide in a corner and admit that I always thought it was "Eorzea"
Silly Cyoide, Eorzea is for adventurers! But don't worry, I admit I thought it was Eorzea for awhile until I checked a wiki site. SE went with some strange names for their places and lands this time around. Vana'diel was so easy to remember since you always heard it. Yet you rarely hear them call it Hydaelyn, normally "Eorzea" is the name you hear.
