What caused Eorzeans to lose their memory of the 7th Umbral Calamity?

What bothers me is that if you're not a legacy character, what happened to the original heroes?

According to this wiki page, it stated "The characters created since A Realm Reborn are just adventurers who travel to a city-state to start their journey, making the warriors of Carteneau as heroes who perished in the battle."

Louisoix would still have done his thing, but its likely he didn't save the Warriors of Light in time.

The wiki isn't generally reliable for lore, since anyone can edit and add information they think is true - but may be misinterpreted, fanon or just making things up as they go along.

Even worse, they take the usually-benign "any information is better than no information" wiki principle to an extreme, immediately reverting it if you try to remove misinformation unless you can provide a citation to the contrary...when it didn't require a citation to add it in the first place. "How about you prove that Thancred's favorite ice cream isn't mint chocolate chip?" Someone finally managed to get "ceruleum is made from draining crystals" off there, though, so maybe there's still a chance things like "the Fall of Ala Mhigo was the Third Great Hyuran Migration" will get hit from orbit one day.

It's a great resource in general, but FFXIV coverage (if not their citation policy as a whole) needs medicinal action ASAP.

You're not wrong, but this is the only source I can find regarding the matter and thought it'd be interesting to point out. To add to your point, what I quoted hasn't given a source as well so I'm perfectly aware it could be wrong.
