As I mentioned earlier, the Everqueen has some really bullshit hax Life magic, like once she restored a Chaos champion from a 8-foot brickhouse brute into the scrawny mongrel he was before worshipping Chaos and gaining their gifts.
Since we're in with the Asur and definately earned a vacation, maaaaybe we can justify a trip to Ulthuan and petition to see her?
Yeah, that's a tall order. We might have some goodwill from some Asur, but meeting the Everqueen? At this point, I suspect we'd be laughed out of the room before we could even finish that sentence.
That was more because she is such a font of purity that she removed all his Slanaesshy Chaos blessings with a touch and then let them come back all at once turning him in a chaos spawn when she let him go. The point I was making is that we do not need her to fix this and the chances that we could get in contact to ask before things were decided is very very low.
