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

[EaraGrace]

Should we be concerned that the WoL brought back a crystal containing the soul (and some aether) of a being that *hates* being cooped up? What if it starts to absorb ambient aether like our new friend, can it break out?

I believe it was mentioned that undoing memoria crystals is not a known possibility atm. Perhaps in the future that will change, but for now I think the risk is held to be minimal. Unless of course there’s something we don’t know.

In addition, it seems sealing aether in the form of a memoria isn't simply trapping a soul inside a crystal similar to what happens with the ascians and auracites. Instead, it's a stasis form of aether where it's crystallized.
While this explanation is pure speculation, it does explain where the crystal came from, how it works, and probably why it can't be reversed by known means.

Assuming the trial for 6.5 is all 4 elemental fiends together, I'm gonna guess that it will be explained in the future.

May also tie into why Hydaelyn’s crystal reacted to Zero. Her powers are umbral in nature, maybe even light-based.
