Askellon Sector is host to many Forge Worlds of the Adeptus Mechanicus, the greatest of which is Cerix Magnus. It exists in the Mechanicum’s own empire that coexists within the sector. Despite this, Cerix, and to a lesser extent its sister forge worlds Selvanus Binary and Core Theta, are as reliant on the sector as it is on them, for without raw materials from elsewhere, the forges would sputter and grow cold.
