"...I suppose we cannot be choosy about allies in these end times," she concedes.

"What are your aims here?"

"I'm trying to make everyone safe! I don't want the X-program killing people."

"A worthy aim," she says. "What's your plan for the King and his Knights?"

"I'm trying to make people safe while I figure out what's going on here and what to do. I got here only a bit ago so I don't know much, and then stuff keeps happening."

"It speaks well of you that that's your first priority. Still, if you disrupt the royal plan they'll notice you eventually. You'd best be prepared to fight or avoid them."

She continues, "May I assume, then, that you have no plan for the space crunch? When the survivors are all 'safed,' but they continue to grow and the server is full?"

"I can make places and stuff, and I could try imagining a whole bunch more place for people to be in. The dream-place is infinite and someone imagined that."

"Good enough for me, Child."

And she enters the portal. As far as Boogey can tell, they've cleared out the desert.

She steps through the portal and makes everyone safe, though she makes the flare one safe separate in case something goes wrong.

The flame creature does in fact extinguish, revealing burnt, scarred skin under its safety cloak. But its complaint of "Augh, so cold!" is quickly drowned out—

The angel screams, her body going rigid. Wherever the shadow touches, her feathers darken.

UNSAFE!

The shadows go away and stuff starts working like it's supposed to because Nausicaa heavily believes things should work like they're supposed to - 

No longer protected from its own flames, the fire creature resumes burning, with a sigh audible amid its crackle.

The angel stops screaming; the lighter and darker colors play over her for a minute, as though unsure how far back to go.

Eventually they settle somewhere in between - not the blacks she'd dipped into, but more nuanced than the whites and pinks she'd worn before.

"Ah. Glad that's over with. Perhaps I should have warned you, child - my kind aren't made to compromise with darkness. But in this case I thought it worth it."

"Do you want me to try putting the shadow blanket over you again then? I thought it might be hurting you..."

"I expect I'm as fallen as I can be, now, it shouldn't hurt me any further."

"Okay..."

And she safes the angel lady again.

"And voilà, your lady of shadows. Falldown Angewomon at your service." She strikes a curtsy-esque pose.

She curtsies back. "I'm glad you like it!"

("Now you're tempting angels to fall to darkness?! I don't feel evil yet, but I'm watching you!")

"We good here, or there more to do?," asks a now-safed rock being.

"People are okay to go back! Boogeyman will open portals for people."

So they mostly go back.

"Got a plan B or shall I take my chances?"
