Well, that's heartening. He'll go in the door, then.

The door leads to a lobby with potted plants and backless benches and a sign reading, in the same four languages, "press button to page someone", next to a series of labeled buttons with various names in various alphabets beside them.

This does not seem like a setup that is meant to deal with random walk-ins at all. He has no idea which person he should be paging, after all. Maybe they have some other way for the public to get in touch with them that isn't this; can he find anything like that if he tries looking them up online?

They have an email address!

He... needs an email address of his own, and then he can email them to ask what they do and if they're hiring.

Getting his own email address is not hard.

He doesn't get a reply right away.

He'll play the summons lottery again while he waits.

This circle is someplace with higher gravity and it's outdoors! On a beach! "Hi!" says the summoner, apparently not instantly noticing that this is a really weird looking angel. "Huh, you don't have wings." She speaks English and a few words of Mandarin.

"Haven't figured out how to make them fit with the rest of my setup." His articulation is much better now but his voice still has an odd metallic echoey ring to it. "I'm looking for short-term work that doesn't take specialized skills I don't have, is that what you're looking for?"

"Shouldn't be too hard! There's high bacteria levels in the water today and we just want you to wade out there and be a water filter till we can reopen. Don't hurt the sea creatures. Sound doable?"

"I think so. You want the water just plain?"

"Plain for seawater. Salty. If you don't get the mineral concentration exactly right that's fine."

"That sounds doable! I came here hoping you'd have a summoning book - you know, from your end, I know what it's like from my end - but I'd consider other things if you have other things."

"Huh, I've never - I have my summoning textbook from university and I don't need it anymore. I will give it to you in exchange for five hours of water filtration or until our test buoy reports safe concentrations, whichever comes first, deal?"

"Deal!"

The summoner sends a gofer to fetch the book, and supervises his angel at work in the water.

He hasn't studied local bacteria but he does know a bit about the microorganisms native to two different unrelated biospheres, so he's pretty clear on what this person probably wants. If he can aim for the bacteria specifically he'll turn them into water; otherwise he can... turn the water into water but specifically into water that doesn't have bacteria?

With his skirt wet enough to cling to his legs it's clear they're not human-shaped.

His summoner is looking at him but it's not clear if this is because he's weirdly shaped or because he's Supervising.

He can't aim for the bacteria specifically.

It would probably be very useful to try to engage the alien human in small talk but he has no idea how he'd go about that. He makes water into different, cleaner (but still slightly salty) water for five hours or until the buoy is satisfied.

The buoy is satisfied in hour four. "Great, thanks!" says the summoner, handing over the book.

Meanwhile, back in Haven City, things are still happening. Urru talks to some other lurkers about specs for a lurker city. The minister writes Cam about what she wants from a house and lists off some other ways she thinks she can be useful to him; she also mentions that someone else has just freed several lurkers and destroyed some Guard property in the process, and that she's telling anyone who asks that she hired this person to do pentesting for the ministry.

Who was this? Does Urru know any of the escapees?

Seems to have been Jak, and Urru can tentatively put names to three of the lurkers in question but doesn't know them well.

Cam will attempt to put Urru and the escapees in touch so they can collaborate on the city, since there are different kinds and everything.

She can try to get them and the other people she knows who have ideas about lurker cities talking, sure. (Seems unwise to mention that she suspects they already are or will be in touch with each other whatever she does about it.)
