Nexus Prime

I carry letters. Paper ones, by hand, through doors, because nothing else survives a crossing reliably and because people will pay a great deal to put a specific object into a specific hand. Every route I run touches Nexus Prime. There is no route that does not.

The rift it is built on

People describe Nexus Prime as a city around a dormant rift and then move on, and the word does the wrong work. The rift is not finished. It is not inert, it has not closed, and it is not going to.

It is held. Ferrum engineers maintain the physical anchor-rings and have done since Year Two, in shifts, indefinitely, and the maintenance schedule is a public document that almost nobody reads. I have read it. There are four rings. Two are original and two were added after an incident the Concord minutes describe as "an adjustment". The document specifies what happens if a ring falls below tolerance, and the specification runs to two pages.

The largest city in the merged multiverse is a maintenance contract that nobody has yet failed to renew.

What is above

The Concord sits here — the closest thing the Nexus has to a table where worlds speak to each other, and where Eira Mossglass has spent fifteen years hearing arguments before the people having them notice they have started. Astran engineers, Vale diplomats, Meridian liaisons who are not officially present, Reachguard quartermasters, half the Vanguard's administration and all of its paperwork.

It is also, and the pamphlets skip this, a city of queues. The gate has a criterion. The anchor radius has a limit. There are districts where a Gloamdeep accent gets you served last, and everyone involved would deny it.

What is below

The old aqueduct labyrinth, which is Gloamdeep's and older than the surface city sitting on it. It is a natural rift maze, it cannot be reliably patrolled, and the Gloam Exchange operates in it without paying anyone rent.

Runners move under the whole city unseen. As a courier I will say plainly that they are better at my job than I am, that a letter routed through the tunnels arrives faster than one routed through the gates, that I use them, and that I owe a favour for it which has not yet been called.

The thing nobody says at the Concord

The Pale Broadcast, out in the Phantom Expanse, announces crimes that have not happened yet, and preventing one makes the signal stronger. That is a Phantom problem and the Expanse is welcome to it, except for one detail that has been in the record for six years.

Every prophecy ends with the same image. Nexus Prime going dark.

Not falling. Not burning. Dark — which, in a city whose light is four rings and the working they hold, is a very specific claim. The Concord has received nine separate briefings on this and has scheduled a tenth.

"Everyone here talks about the rings as though they were geography. They are a rota. There is a list of names, it has to be filled in again next month, and so far it always has been."
