Lore

Does time revolves itself, or does it end?

That is the main question of the lore ingame. the 2 gods who created the world dit not literly create the world but rather create the time line.

Both gods where needed to create the time line, Xion & Veldin. Xion is seen as the start of the time line, and Veldin as the "end" for some and the "re-starter" for some. The time between or after the gods is called Limbo.

Religion
There are 2 prime religions the one is based on time revolving in circles, and the other is one is based on time ending

Time Circle
The time Circle is based on the gods creating time but there is no ending to it

Xion created the begin of the time line, and Veldin Re:Codes the time, so time would repeat itself.

The limbo in this theory is located out of the time circle.

The ones who beleave in the time circle try to bring Veldin closer to there time so he is able re-start it, and a new world wil start.

Time Line
The Time line is based on the 2 major gods creating a begining and an end of the time, Xion the begin and Veldin the end. this just means that the time was started, it has to end.

Limbo is located after the end, noting exists after the end of time.

The people who beleave in the time line try to bring Xion back to the world to Re-Start the world to save it from ending.
