"Yes, I can do that."

"Wonderful." 

Okay, well, there are a bunch of armed groups of people with only normal amounts or less of thing-wrong-with-them fighting the demons. She picks the largest and most successful-looking group and bops over.

”Hi, I have an unlimited,” technically inaccurate but it doesn’t run on spell slots and she isn’t, like, immediately about to run out of mana or anything, “short-range teleportation ability, if I can get you guys somewhere halfway defensible can you protect wounded.”

“—Yes. The temple of Iomedae, over there—“

Leave it to Iomedaeans to build their temples defensibly—although actually that’s definitely a good idea here in demon borderland. Okay. She waits a moment for the commander to give appropriate orders and then starts teleporting soldiers one at a time into the temple.

They immediately start fortifying all the doors and windows.

Excellent. She drops kiddo with them and then starts gathering survivors.

And when she hits something of a lull in finding survivors, the half-orc woman who seems to be in charge asks, “What’s the range of your teleportation ability?”

“Uh—a little over three hundred feet, I think.”

That’s not ideal, but any kind of at-will teleportation ability is a resource they weren’t expecting to have. “How many passengers can you take at a time?”

“That is—sort of complicated—uh, ‘at will’ was actually a huge oversimplification. I, uh, don’t have spell slots? Instead I have a thing called ‘mana’ that I regenerate over time, at a rate that depends on stuff, and any given spell costs a certain amount of mana, and teleporting more people at a time is faster but costs more total mana than teleporting the same number of people in smaller groups.”

That is very weird. This person does not detect as Evil, but there are ways to fake that, and “demons playing silly buggers” happens a lot more often than people with really weird magic.

But then, “demons playing silly buggers” just happens a lot anyway, and it’s not like weird magic is unheard of. Not using spell slots at all is weirder than the fact that the evil Count Arendae channels positive, but not by that wide a margin.

And being incredibly suspicious of helpful people is Hulrun’s job.

”Okay. This place was a good choice in the short term, and useful for collecting the survivors clustered around this area, but in the long term I’d rather have a base less centrally located to the spot where Deskari showed up.” And Terendelev was horribly murdered.

“That makes sense. Do you have anywhere in mind? I, uh, only arrived in Kenabres today.”

“Someplace that we can get out of on our own if we have to—demons can teleport too.” Not literally all of them but enough that it’s not worth explicitly qualifying. “If the Gray Garrison hasn’t fallen, that would probably be the best choice.” Especially since it looked like that was the direction Deskari launched the Wardstone in. It’s probably fallen, though. 

“Which is—where, sorry? Uh, my teleportation targets off of distance and direction, and the better I know my destination the less precise about those I can afford to be.”

Most of the rank-and-file present would have no idea what the straight-line distance is between the temple of Iomedae and the Gray Garrison, but fortunately Irabeth has occasioned to work with people who could, or had familiars who could, fly, such that it happened to come up. Direction is easier. 

She reappears a few seconds later. 

"Gray Garrison's fallen," she reports unhappily. "--Also there's a giant glowing magical obelisk jammed into it? That seems important." 

"The Wardstone. Damn. We need to recover it." 

"If we can find a good place to put it and I can accumulate enough mana I can teleport it. It'd be, uh, way more mana than I have right now, though, probably there isn't a good spot within one or even a few hops and also the Wardstone is...uh...it has people in it. Kind of a lot of people. Dunno what's up with that."

"--It what?"

"--Okay, so--my existence is complicated, there is a sense in which I came to exist only a few hours ago and a sense in which not that--and I am missing vast chunks of basic background context, what is a Wardstone?"

"The Wardstones are a gift from the goddess Iomedae, placed by her herald in Kenabres and other cities and fortresses across the Worldwound. The chain of Wardstones forms a protective barrier that stops the expansion of the Wound and prevents demons from crossing. Deskari picked it up and threw it after he killed Terendelev."

Terendelev must be the dragon. "...Demons were showing up before she died, though?"

"Yes." She isn't able to fully prevent the exhaustion from creeping into her voice. "We were given a warning, by an old elf called the Storyteller, that something was wrong with our Wardstone, some days before the attack. We hadn't yet been able to figure out what, or how it could be repaired, before--" she gestures to one side, indicating the entire clusterfuck.

"...Well, the Wardstone had people in it, and the people had a certain degree of not-okayness. Taking people who are not okay and causing them to be okay is sort of my whole thing, so--I might have an angle on that. Again, it'd take kind of a lot of mana, though." There were a WHOLE BUNCH of people in there. 

If this is a trap--if all the helpfulness up until now has been bait for a demonic trap--this is where it snaps shut. 

"What do you need in order to regain mana?"

If the answer is human sacrifice she's going to smite evil and try to kill her as fast as possible before she can teleport away.
