Magrathea is an ancient planet located in orbit around the twin suns Soulianis and Rahm in the heart of a dark nebula. Magrathea is a planet whose economy was based on the manufacturing of other planets for the wealthiest people in the universe. It was the people of Magrathea (known as "Magratheans") who created the Earth. Magrathea is considered the home of the industry of "Custom-made luxury planet building." It was a market aimed at the richest of the rich, during the days of the former Galactic Empire. The Magratheans would design and create entire planets for wealthy clients. They were so successful that Magrathea became the richest planet of all time. However, this resulted in the rest of the galaxy being plunged into abject poverty and the economy collapsing. The planet then faded from memory with most people believing it to be just a myth and that it was just imagined by some child and it some how spread (which makes absolutely no sense, why would a child dream of economics?). Amongst the clients who asked for planets to be created were a race of hyper-intelligent pan-dimensional beings who asked the Magratheans to create the Earth, which was not a planet, but a super-computer designed to calculate the ultimate question to the ultimate answer to life, the universe, and everything. Amongst the people who worked on it was Slartibartfast, a coastal designer who won an award for his work on Norway. The surface of the planet appears to be dead, with the Magratheans kept in cryogenic state, not to be awakened until the economy was good enough to pay off Magrathea's expensive services. The surface is described as "Blighted". The book says that, "Bits of it were dullish grey, bits of it dullish brown, the rest of it rather less interesting to look at. It was like a dried-out marsh, now barren of all vegetation and covered with a layer of dust about an inch thick. It was very cold." They were later awakened for the reconstruction of the Earth (the Earth, Mk. II).
