Concern over memoria crystal being brought over to the Source...

[Alleo]

If they weren't the same I don't think the writers would have Y'shtola even mention the auracite. And I mean, both of them were used by heroes to seal away Primals/Eidolons then use those sealed Primals' powers. It's easier for me to believe Zero that the crystal just had different names in different parts of the world, rather than two different crystals that both did the exact same thing.

Maybe the Auracite are the versions of the Memoria crystals that the Ascians changed so that they would corrupt the people wielding them. After all even if Zero herself might have been shielded by the effect because she was never a full human anyway (and that is pure speculation on my side), her mother used her power for quite some time with seemingly no problems.

But wouldn't the fact that she was tainted in the womb into being "part" voidsent imply that the memoria were already leaking eidolon essences before she was born, given her mother was a memoriate?

In addition to this, Zero literally tells us that the memoriates were swayed by the power inside the memoria and started using it to spread darkness. That's the same thing Unukalhai said back in HW.

I guess it could have been the crystal. Or the darkness came from the summoned beings. Hopefully we get an answer to that in the future.
