Crateron is the home planet of Pietors.
Crateron is a rocky planet with a sulfur atmosphere. It is covered in craters, mostly created by Pietors. The planet orbits an ultra cold red dwarf star; as such, it is very close to the host. Due to volcanic eruptions, some Pietors often get sent to space close to their star. Luckily, the species are resistant to fire and magma, which only evolved further.
Nothing is known about Crateron's history due to its hard-to-reach position.
Crateron is a play on craters, the geological features the planet is covered by.
