Right after you defeat Altima on the Airship Graveyard, in Final Fantasy Tactics: War of the Lions, she utters:

Ultima: Impossible…this end to meet…I see it now, too late. In you…his blood, my vanquisher in times…long past. But not so soon…shall I accept defeat…

and the original game:

Altima: No… This can’t be… You’re the descendant of the one who killed me before. No…I won’t be beaten… I will not be beaten…

She’s most likely talking about Ramza, as he’s necessary for all story battles. If so, who’s Ramza a descendant of? It could be one of the Zodiac Braves. But then, also consider that our party in Final Fantasy XII defeated Ultima as well. And as we know, Mustadio is a descendant of Balthier.

Could Ramza and the others be a distant relative from someone each in Final Fantasy?
