The mayor runs out of things he wants for town property. Then he tries to collect and order requests for things so Cam isn't just listening to people shouting what they want. He's also balancing the town's weight budget, and eventually asks him to expand the islands' floatstone a few feet. He could be here a while if he doesn't decide to be done at some point.
Cam stops at the point where he would have to literally grow the island bigger in order to make them any more things. "It's been fun," he says, "but I think it's about time I checked out the stargate."
He can go in through the giant ragged hole in one of the bulges along the side, revealing cross sections of rooms and hallways and what might very well be the remains of a reactor of some kind.
Cam departs his ship and hops in, making himself air. He inspects the station with fascination.
It's pretty much all various bits of engineering from airlocks to power relays to server rooms, reactors, and 'alignment coils'. There's elevators, a station train, a control center, housing and facilities for ten crew. The most largest individual rooms are labelled as the 'Primary Entanglement System' and 'Backup Entanglement System'.
It's full of bulky, vaguely server-like boxes trailing wires in every direction. The centerpiece is a large sphere whose top layer is some sort of ceramic, with plenty of ports for wires going to the boxes. Some of the wires and boxes are missing or torn in a way that looks like a human did it (as opposed to sudden decompression).
There's a lot to sift through, in a mix of slightly off his Earth's standard English and similarly off-standard German. Personal journals. Lots of correspondence and forum posting. Credited as partial author on eleven scientific papers about obscure particle physics and primary author of one. The piles of bureaucracy reveal what he's looking for: Daily reports on the status of the entanglement systems. Efficiency and calibration and diagnostic. Personal notes on the project. Presentations attempting to explain the engineering concepts to upper management. Blueprints.
According to these documents this world's physics are not quite the same as the ones he's used to once you go below the atomic level. The math is complex, but the entanglement system uses this to convince one unit of space to be in two places at the same time. This allows faster than light communication and, with enough convoluted supporting systems, FTL travel.
