Nano (catalogue number MPB-1001001) was a dwarf planet located far out in the fringes of the Dark Nebula of Soulianis and Rahm. It was built by the Magratheans, who sold it to Zaphod Beeblebrox, who then sold the planet to Hillman Hunter, who paid for most of the planet, along with rich people he "led" back on Earth, before it was destroyed. The name "Nano" is the very same name Hillman Hunter called his grandmother. Nano is a Magrathean-made planet with three tribes, two of which were originally set up, with the third, the fitness trainers, coming from the Tyromancers and Nanite towns.
Innisfree is the only continent on the planet, named by the Nanites' leader, Hillman Hunter.
Hillman Hunter employed the god Thor to look after the Nanites. Nanites pay taxes to the leaders of the universe, saving them from the Vogon ship which would have otherwise wiped out the Nanites, Tyromancers and the rest of the people on Nano.
Tyromancers are the enemy tribe of the Nanites. They believe in the Cheese and are an alternate version of the Nanites themselves, as revealed by Zaphod Beeblebrox.
