Midgardsormr and the Crystals

[Viridiana]

I doubt Midgardsormr took the blessing so he could use it to make his body. He's in Mor Dhona, the aetheric fountain of the world - no extra aether needed.
He removed it to test us, and stop us from draining Hydaelyn any further since she's very weak atm.

Agreed. Though, I kinda wonder how much we've actually been draining Hyd since Praetorium. I mean, we did the hard mode Primals, sure, but it's hard to say how much, if at all, that drains Hyd. Especially considering that some of us went on to do extreme mode Primals without the blessing.
