Earth, the cradle of humanity. All walks of life survive in this machine world, though few are thriving. If you find yourself here, stay above the floors. Take a taxi between the towers if the skyways make you nervous. Look out your corporate apartment window. Below the flower gardens, cloud plazas, and skiffs weaving through the towers, there lies a different world.

The floors. Vile, overcrowded places tucked so deep between the cracks of the towers sunlight loses its way. People change without Sol’s gaze…

Don’t worry, they won’t bother you. We’ve paved over the bad parts, and our elevator network costs a fortune to them (but just an hours’ work for you, dear employee!)

So long as you do your job well, you’ll have this cushy apartment. You’ll never see the guts of the machine world, nor the millions of mechanics that keep it running. Your air is filtered by their craftsmanship.

Only the best climb their way from the undercity. It’s a good idea to keep it that way.
