The endless floor supports caves where people hide from the dark seasons. About 536,041 souls live inside these underground chambers while the surface waits for nineteen days each year.
A large cargo door sits in a museum of things that have come through it.

No one may strike another in the museum where the cargo door stands open; violators face exile to a sector barred from returning.
from Gate Watch Song, by Yagu
The D-Station sector 6 floor stands wide enough for Earth's whole surface to hold more than a hundred million gates. Ten credits pay for a single head to pass while a thousand credits buy passage for a hull.
The oldest living person rules the whole nation until death claims them.
from Dark Season Sermon, by Ziyinan
Fuel is dug, pressed or grown here and sold to every world the gate reaches.
Stored fuel runs low in bad years because famine returns while the stores are never quite enough for everyone.
from The Fuel Account Book, by Gukun
The labour trade grows into slavery between the fuel diggers at Togizo and the merchants who transport them away. Compasses spin wildly near the surface because magnetism does not work here and motors built on it stop running.
