So I've created a new map of Spira. It's not perfect, but at least it's my own work apart from onionskinning 3 different Squenix maps, none of which agree, to get the rough outline. I swear Bevelle has moved a titch south between X and X-2!

A cropped version is now in my LJ sticky post, and I'm gonna add it to the AO3 edition of Love Her and Despair. Yay AO3 for allowing us to embed fanart!
A few geekly observations about Spira's map.
1) I never noticed before that that archipelago west of Baaj looks a bit like Japan. I have the suspicion this was the original home of the Al Bhed, but I don't know why I think that (except Rikku did mention another island, I think).
2) This fabulous map is a fan's high-res scan of one of the two in-game maps, with most of the Spiran glyphs transliterated. "Wilderia Continent" is the name of the continent containing the Calm Lands and Gagazet, while "Djose Continent" is everything south of Bevelle.
3) On that map, there are about 8 tiny labels whose glyphs are too small to make out. About 6 of them appear to start with "Temple of Yevon [something]" in the same style as "Temple of Yevon-Djose". From this I deduce they are smaller villages which have temples, and that some temples don't have fayth (otherwise, Yuna would've had to visit those, too).
