"Like... legos?"

"That's some kind of toy used for building I think... so maybe?"

"Yeah I have no idea what would happen if you tried that here where we mostly have physics. Like not mostly by an overwhelming margin, but mostly."

"Does anyone else have a guess? I'm not sure if that's the try it and find out kind of no idea or the if you're going to try it make sure nothing you care about is nearby kind of no idea."

"There's tons of room to go somewhere nothing anyone cares about is nearby but not in Hereafter, almost all the cared about things that can be wrecked are here!"

"That makes sense, I'll hold off on experiments with actuators for now. It sounds like pumps are the best way for you to get electricity."

"Pumps meaning plumbing? Yeah. If we build a big tower, and put things that produce water on top, we can turn a turbine. Right now we're on solar but Limbo has a daycycle so it only works half the time."

"Each pair of pumps can move up to 256 cubic feet of water per second from the inlet pump to the output pump if the inlet pump is fully submerged."

"And these... don't require any power of their own, somehow?"

"Nope, you just need to wire them together with a quarter second timer."

"I know all those words individually but bet you're about to describe something weird and lego-y."

"Wire is an intangible and usually invisible thing that comes in 4 colors and that you can only see and change with the help of certain magic. You can use it to connect various devices and activators together. A quarter second timer is an activator that triggers every quarter of a second while it's on."

"Yeah that's extremely - not even lego-y, there aren't intangible invisible legos -"

"Our worlds do seem very different. Someone I talked to before said that mine is Videogamey. I don't quite understand what that means though."

"After my time."

"Oh, I know a guy who has a gaming rig. He's super protective of it, though, it's an import not a Thing."

"I would love to see it if I could but if not that's fine. Oh, you probably know the concordance schedule, I want to figure out if my magic can let people move through the concordance boundaries. I had one idea before but now I have two others. I guess it depends on part on how they work and how big they are."

"The next one isn't for a few years."

"Oh... that's a long time to wait."

"Yeah."

"Well, in the meantime, maybe you can help me be a bit less haphazard about giving out magic and magical items. Also, I would actually like to see the museum at some point."

"I can show you the museum." The woman who's been doing most of the talking leads the way. "Unfortunately nobody who distributes things from the train is expecting a delivery right now."

"I'm happy to start with the museum."

"There's better museums but not in this world."

The museum is made of limbo-train shipping containers, of course, with apertures cut into them and some of them stacked on top of each other. The next-most abundant resource in Limbo after dirt and seawater is wood, and there are ladders between the levels, made from tree branches harvested from Thing-trees. The outsides of the shipping containers have been caked with mud and decorated with mosaics of broken glass and ceramic.

Inside the first room there is a scale model of inhabited Limbo, made of real Limbo dirt sealed in resin, more resin for the sea, and colorful representations of the cities and notable Things and the train route. The label says it is current as of 2170. There are pictures of previous editions of the map on the walls.

"Neat, do you know how far things go, do they just go forever?"

"That's what demons tell us but newcomers appear near other people."
