The World Map of FF: Another Time
Towards the end of Final Fantasy, the player party travels 2,000 years into the past to stop a time loop started by Garland and the Four Fiends. By doing so, the timeline has had two millennia to diverge from the original game. This is the basis of the story behind Another Time.
During the 2,000 year divergence, there have been some very notable changes. Most notably is the landscape: the Cardia Islands in the mid-north are now one giant island, the rivers around Gurgu Volcano is now a winding valley, the Sunken Shrine is not-so-sunken, and there's actually snow in the northern areas!
However, the most important change story-wise is the charred remains of the Cornelia plains and ominous looking Chaos Temple. Obviously playing through the game will tell you what has happened, but I'll try to fit it in a future post if I can.
Stay tuned for more updates and news, and please comment/question when available!
