Arctic's agent gets the details, and accepts on her behalf.

Arctic is okay at portal finding. Only okay. Much of her work is not dungeon related at all because she has great range; she finds lost hikers and missing children and such.

The trouble with finding portals is that a lot of times, if they're hiding, they're positioned in such a way as to make her job really hard. Arctic can "zoom out", but not through whatever her power has decided is the ceiling. Tree canopy? Piece of cake, that's not a roof, she goes "up" till she's observing as though from space and can spot a river or bit of coastline. Inside a dungeon, which she'll do for big ones with known lists of victims? The dungeon boundary itself is the ceiling and she can pop up past however many layers of foam tile and carpet as the dungeon cares to stack, though she's better in more open ones just because this gives her more map-style visibility. But a hidden dungeon portal is sometimes in, say, a crawlspace, a completely dark subway tunnel, a random attic, a literal cave. She'll get a view of it, even (if she pushes hard enough) the ones in the dark will give her a glimmer to describe. But she can't zoom out and find it on a map.

This one, though, is almost certainly going to be by a road, what with the vans. There are a finite number of road tunnels in the San Diego area. "I can't see much, it's a tunnel" is itself many bits of information.

She snuggles up to Pyramid, whose ankle is tied to their big cozy guiding recliner to prevent wandering off post-dungeon (there were Viking squirrels), and, all the way from their own silo across international borders, she has a look.

What does the portal look like?

In an evacuated, unpowered, nearly-unlit nurse's room.  Looks like it would be in some kind of childcare-central facility, given the intended audience of the posters on the wall and the bottle of children's acetaminophen that's fallen on the floor.  The intensity of the sunlight suggests its window is east-facing.

Well, that's not near a road at all, but it's information. She sketches the layout and looks for the expiration date on the bottle and reports the window direction but she cannot get out of the building.

The expiration date is about 2 and a half years from now!

The DRT research team is composed of the type of person who, when asked to find which building in San Diego(a city with well over a million people in the actual city, nevermind the outskirts) contains a children's nurse's room with these dimensions that faces east, say 'No idea!  Give me half an hour.'

They pull the doctor's and nursing licenses of every person who works in the San Diego Metropolitan area.  Then they pull building plans for every building that a medical professional works in and plausibly could treat patients in, setting aside anything that doesn't have an east-facing window.

One analyst Sarah Tsang, would like to check if Arctic's power does audio as well as visual reporting.

Nope, eyes only.

Shit, she very professionally doesn't say out loud.  Okay.  What if they......fired colored flares straight in the sky and used that to triangulate the position?  ... that would probably work at night, it's a little overcast.  If Arctic thinks a flare fired outside would be visible from inside the dungeon portal room, they can try it.  Otherwise she'll get back to pulling building permits.

If it's colorful, yeah, should work. Not a traffic color ideally, she could get red off a car. Have they considered just having drones look in the windows of plausible buildings?

That's gonna have to be the next step.  They would rather narrow it down a bit rather than fly drones across outside this many buildings in San Diego.

A few minutes later, they ask Arctic to get eyes on the portal.  Shortly after that, she sees a weakish flare of green light from probably-northeast.

"Green," she reports. "From the left edge of the window if you were facing out, I think."

"Left side...facing out.  Okay."

A few minutes later, they'd like to know if she can see a purple flare?  They're trying it a little south of the next one, they want to give triangulation a shot. Or at least narrow down the location.

"Yeah, I see the purple, that's brighter."

Okay, so it has to be somewhere near here. That narrows it down to eight potential locations, but it's probably one of these two.  They've got a drone with a red-lensed flashlight, is it going to be a problem if she lets them know when she sees the red light?  Hopefully it'll be done within 15 minutes?

They can save on power use if they just send her drone photos of the rooms and she can say if they match........

Oh!  Yes.  That works, thank you.

Three minutes later, she starts receiving the relevant photos.

Not that one. Not that one. The tile matches in this one, probably the same building - yes, there!

Hell yes!  Looks like it's a pediatrician's office.  They're going to be mildly annoyed about this one, it's on the third floor.  But they have it.

San Diego appreciates your assistance, Arctic.  Doing this without your power would have taken quite a while, and the DRT analysts are glad that they don't have to keep looking at building plans anymore.

No problem!
