Here they are, appearing in a flash of blue light.

"Good morning."

They were all holding hands for the teleport, but the short statured one with purple hair stops that immediately. "Hello, status on saline and sprayer acquisition and triage setup?"

Baek Ji-woo: not a woman of much formality in a crisis.

Valerie has not personally worked with Baek Ji-woo before but she does read the notes DRT coordinators leave on profiles when receiving extremely capable international espers.

"When I last checked the saline is acquired and there's a likely source for the sprayers, but Lt. Jin here has a more up-to-date understanding of the picture and is ready to take you to where triage is already happening," she says, smiling and gesturing to the man to her left.

"Uisa? If you'd follow me,"

"You might want to check home center stores, the sprayers will not be properly sterilized, but it is all going to be getting coughed up anyway," she says, but - yes okay she can go instead of bossing around Valerie in particular.

And Ji-woo is gone in a poof of smoke competent medical logistics.

"Mr. Min Woo-young, Mr. Seo Tae-hwan," (she mispronounces their names slightly, in the way English-speaking foreigners usually do) "on behalf of the entire city, thank you both so much for coming out here on such short notice. I'm Valerie Novak, DRT Regional Coordinator. Do either of you need anything to eat or drink before we drive over to Infested Wasteland's portal?" She can brief them on the way over, it'll be about a ten minute ride.

"...no but I do need to ask if you're really attached to the car ride."

There's a moment of visible confusion before the gears click, but she's too professional to look embarrassed. "Ah."

Her 2-in-1 is already in tablet mode - she unlocks it as she asks him what info he needs teleport the three of them to the portal site.

"Honestly, cheapest to just text me the coords," he says, opening his commscreen. The overall power expenditure of using coordinates is less than him doing it personally and so if he just feeds the battery the same amount it'll come out better.

She has to call a guy real quick but then he can get the coords sent straight to his commscreen, yep.

Vworp.

There was obviously a building here, at some point. There even more obviously isn't, anymore.

The nearby towers (several of them obviously marred or worse by debris or deeper structural damage, but all still standing) give a good guess as to their former comrade's height.  

The air is full of dust. There's a lot of noise, of the kinds you'd expect from dozens of emergency response workers trying to sort through rubble and establish a perimeter and set up seismographic equipment.

The portal hovers menacingly in the air above them. In the distance, the unmistakable sound of a worm screaming can be heard.

"Shit," she says, before she can catch herself. She's seen the video feeds, but...

"Holy shit."

"You can stop it," Woo-young says, encouragingly. "No more worms are leaving this dungeon."

"I know. Just... Jesus."

She composes herself. "How familiar are you with Infested Wasteland?" It's behaving weird, presumably for confluence reasons, but she's not sure if they have a baseline or not. 

"Only what I read in the briefing document. Starts out by hiding its portal, spews out sandworms that can swim through concrete, they eat people and bring them back inside, it's a sandstorming desert."

She nods. "All correct. This time around portal wasn't hidden, but it seems like the worms are better at hiding their tracks, somehow. We're still figuring it out, but we expect them to show up here once they do return, just with very little warning. When one does, we'll be looking to have you stop it in place." She says this last bit to Tae-hawn directly, of course. 

"Can do. How, uh, big are they? Usually?"

Here's a picture of one breaching at the ROM! It's pretty big.

Can he guesstimate the mass of one?

Substantially more than a commercial airliner!

...but if it helps, the individual segments of worm probably only weigh as much as a minivan packed for camping with a family of 5?
