Earth
Birthplace of Humanity and capital world of the People's Republic of Terra. The Mother World. Every Terran citizen is taught to revere it from birth.
Fifteen billion people live here, roughly ten billion more than the planet was designed to support. The solution, applied over centuries, has been to build up and out. Earth's population centers are vertical megacities connected by high-speed transit networks that move millions per hour. The old national boundaries are historical curiosities; the planet is divided into administrative regions that answer to the Premiere's bureaucracy.
Between the megacities, the surface is a patchwork of managed agricultural zones, climate control installations, and the occasional "heritage preserve" maintained for propaganda purposes. The oceans are farmed. The atmosphere is regulated. Nothing about Earth is natural anymore, and hasn't been for centuries.
It's still the most desirable address in the Republic. Living on the Mother World carries a status that no colony can match. Waiting lists for residential permits in the better districts stretch for decades.
The capital city, seat of the Republic government. Renlei Heping ("Human Peace") covers what was once eastern China and houses the Premiere's residence, the Assembly hall, the Republic courts, and the headquarters of every major governmental department. It is the largest city on Earth, which makes it the largest city in the Republic.
The name is aspirational. Renlei Heping has seen more political violence per square kilometer than most war zones.
The ceremonial complex where the transfer of power between Premieres takes place. Built to be deliberately imposing, it serves as both temple and tomb. Previous Premieres are interred here after the ritual execution that ends their term. Visiting the Necropolis is considered a civic duty, and school trips are mandatory.
A complex dedicated to humanity's history before spaceflight, assembled from the collections of dozens of pre-war museums. One of the few institutions on Earth that predates the Republic. The First Museum is genuinely impressive and surprisingly honest about pre-Republic history. The official position is that the horrors of the past justify the necessity of the present.
Mostly Harmless.
