Magrathea

"You're crazy, Zaphod. Magrathea is a myth, a fairy story, it's what parents tell their kids about at night if they want them to grow up to become economists."

- Ford Prefect

Billions of years ago, the planet Magrathea was one of the most remarkable worlds known in the Milky Way Galaxy, at the time of the prosperous Galactic Empire. The native Magratheans specialized themselves in the creation of custom-made planets, specifically tailored in accordance with the needs and whims of each client, and sold at absurdly high prices.

This trade turned Magrathea into the richest world in the galaxy, and eventually resulted in a catastrophic collapse of the Empire's economy, prompting the Magratheans to close down their business and go dormant for the next five million years, waiting for the galaxy to recover. Meanwhile, the location of Magrathea was lost to history, and its very existence was doubted by most people, who believed it to be just a legend.

The planet is located in a binary star system inside the dark Horsehead Nebula, orbiting the twin suns of Soulianis and Rahm. It has a thin oxygen atmosphere which is breathable for humans, but not for Blagulon Kappans.
