Michael used his Unity to force the mana crystals out of the four robed Mystic Masters.
This was the culmination of all of their studying, all of their practice, all of their cultivation. These mana crystals were the pinnacle of all of their magic.
And Michael took it away from them, just like that.
His True Unity mana was the tyrant in the magical space. All the elemental mana had to bow down to it, so taking away the magic from the robed Mystic Masters was as easy as pie.
"This is your punishment," Michael said to them. "You have all done heinous things in order to keep your powers here in the Guild of Arcana. You say that this is all for the good of magic, for the good of the Guild, and for the good of the world itself.
And so, that's what you're going to do. Your own powers are going to be used to keep the Guild of Arcana protected."
With a shove, Eren caused these mana crystals to spread around and shoot towards Sol.
