ok so i was in another thread that turned into waifu wars (how does this happen) WHEN I HAD A STUNNING REVELATION WHAT IF IS ACTUALLY HOW ELSE WOULD SHE BE ABLE TO TELL KAIRI ABOUT A KEYBLADE WAR THAT HAPPENED FOREVER AGO IF SHE WASN'T ACTUALLY THERE but i still haven't actually watched back cover or played all of chi so idk ¯\_(ツ)_/¯
I've seen that theory float around for years that Kairi's grandmother was part of the war but come on, she may be old but she's not THAT old. XD Unless... Ava somehow got trapped in the realm of darkness, got out many years later and went on to lead more keyblade wielders as well as a normal life until she got old and retired.
