How the series should be referenced in ARR.

[Ingolf]

Wait...what is that NPC talking about in the sepiroth reference? Is he actually referencing player names? It's weird that he'd include those x's in there. Unless this is just an easter egg from Square that's poking fun at all of the versions of the name "Sephiroth" people make so they can just have that name.

He's referencing the fact that there were so many variations of Sephiroth and other FF names in XI and XIV I believe.

Adding the XxX was a pretty solid clue to that, and the fact that he says that "So many adventurers have similar names"
