Every Moogle seen in the game comes from the world of Final Fantasy I
- Could explain why Moogle's don't appear in the world of the first Final Fantasy; could be they all found their way there through the interdimensional rift.
The three who perished are the OTHER Light Warriors
- In one of 012's reports, we're told that three fighters were unable to withstand purification and perished. Unknown to Cid, however, they did not truly die, but were sent to World A, aka, the world of Final Fantasy. There, they met the Warrior of Light after he was sent there once Chaos was defeated, and together they formed the first game's Light Warriors.
The Warrior of Light's true name is Cid.
- Given that he is a perfect Manikin made from the partial memories of Cid of the Lufaine, that's about as close as you can get, really.
The entire Dissidia series is the fault of the Light Warriors from Final Fantasy V
- Shinryu began as a Monster In A Box superboss in V. Specifically, he was in a locked chest in the Interdimensional Rift, which was itself a method to seal away various demons that couldn't be destroyed. The Light Warriors were able to knock Shinryu down for the count and went on their merry way without stuffing him back in his box, not realizing he was still alive. Once Shinryu regained his strength, he found Cid by traveling to FF 1 world through the Rift, and the rest is history.
