Trantor

Location from Foundation by Isaac Asimov

Ecumenopolis — the entire planet is one city. Forty billion people, twenty-five million square miles of metal. Capital of the Galactic Empire for twelve thousand years, now slowly decaying from the edges inward.

Trantor overwhelms through sheer accumulation. Every surface is built, rebuilt, built again. The corridors between sectors stretch for hundreds of kilometers — local transit systems move millions per hour through tubes that haven't seen maintenance in centuries but still function because the original engineers built for eternity. The air tastes recycled, faintly metallic, with undertones that shift sector by sector: ozone in the industrial zones, something floral in the Imperial precincts, nothing at all in the deep warrens. The planet imports everything. Every gram of food, every liter of water arrives on freighters from twenty agricultural worlds. Cut the supply lines and forty billion people starve within weeks. This vulnerability is Trantor's great secret — the most powerful world in the galaxy is the most dependent. Hari Seldon saw this clearly: Trantor's fall would not be a battle but a slow starvation, sector by sector, as the Empire's logistics collapsed. After the Sack, Trantor becomes something else entirely — metal peeled back to expose soil for the first time in millennia, farmers living in the shells of administrative buildings, the Imperial Library preserved by quiet scholars who became the Second Foundation without anyone noticing.

Appearance

A world-city seen from orbit as a uniform grey-silver sphere — no oceans, no forests, no exposed soil. The surface is an unbroken expanse of metal domes, towers, and connecting tunnels stretching pole to pole. Atmospheric processors maintain breathable air above the steel skin. At night the planet glows with the accumulated light of a trillion windows. Landing approach reveals the scale: structures rise kilometers high, layered and rebuilt over millennia, the oldest foundations buried so deep they've been forgotten. Heat sinks vent thermal columns visible from space.

Also known as: the Imperial Planet, the Capital, the World-City, Star's End

What They Know

• Trantor imports all food from twenty agricultural worlds — severing supply lines means starvation within weeks
• The planet's metal skin covers every square meter of surface, but beneath it the original geology is completely unknown
• The Sack of Trantor stripped the metal covering from vast sections, exposing soil that hadn't seen sunlight in millennia
• The Imperial Library survived the Sack and became the hiding place of the Second Foundation
• Trantor's population dropped from forty billion to under one hundred million after the Empire's collapse
• Seldon chose 'Star's End' as the Second Foundation's location — everyone assumed the galaxy's edge, but he meant the other end: Trantor itself
• Each sector operates semi-autonomously with its own culture, dialect, and power structure
• The heat sinks that vent the planet's thermal energy are among the few surface features visible from space
