what about when the Ronso fall to Seymour, trying to keep him from passing.
"Master of history, - they've watched as Summoners climb gagazet, die trying to defeat sin.
Lord of naught- they were just the caretakers and protectors of the mountain
Nigh fell in the great deed,- They died trying to make sure Yuna could accomplish her goal.
Lost, not alone." - They lost, but many more were lost helping to rid Spira of Sin.

or maybe before the events of X, and it is talking about when the Crusaders fought before. The Crusaders were around and trying to defeat Sin for a long time. Crusaders fighting sin fthroughout histroy.

I'm at a loss, but will probably kick myself when someone finally gets the answer. Hope neither of these are characters if they are sorry. Someone get this, anyone!
