Legacy Mark

[Myranda]

So if it isn't the mark on the necks of the archons, it may very well be this:

Maybe but it might be a stretch. I have a hard time believing our mark would simply include the Eorzean symbols for 12 (yes, that's what the symbol in the center is: just numbers) instead of something more stylized. Clearly that design does deal with the Twelve gods and perhaps the attempted imprisonment of Bahamut, so I can't throw out the possibility entirely though...

Out of curiosity, where is that banner hanging in the game? Context might help in its analysis.

Edit: Here's a numbers reference using one of my fonts. The original source of the number forms came from the stalls in the market wards, but it's hard as the seven hells to find screenshots of them, I don't remember how I came across them in the first place.
