Accatran is a planet in Beta Quadrant, in the region of the Milky Way that will be known as Segmentum Ultima, on the border of the Ork Empire of Charadon. It will be a Forge World, controlled entirely by Adeptus Mechanicus. Prior to this, the world was uninhabited by sentient species but was home to a myriad of inhuman animal life.
The industrial complex of the planet will ultimately strip it of its hospitable environment, making it inhospitable to all save Space Marines and the cybernetically enhanced Mechanicus locals. Nevertheless, the planet will become famous for unique weapon patterns used by the Imperium of Man's Imperial Guard.
Accatran is from Warhammer 40,000.
