Editing Hephaestus-IV (section)

===Outer Planets===

'''Hephaestus-VI''' is a hive world that contains much of the workforce for the system. 

'''Hephaestus-VII''' is notewworthy for its extremely rich promethium deposits. Evidence of incredibly ancient ruins has been discovered on the planet that is otherwise nearly completely barren save for patches of strangely verdant growth where most of the planets population dwells. It is thought to have been the home of an ancient Xenos species and a much more verdant world before some unknown cataclysm. In the depths of one of the ruins is a chamber which leads deep into the earth, several missions have been deployed down into the bowels of the catacombs, but only very rarely do they return, often with disjointed stories or their cognition buffers wiped. The entrance has since been sealed and is monitored continuously by a detachment of cybernetica cohorts.

'''Hephaestus-VIII''' is a mining world notable for its orbital shipyards. These shipyards are capable of producing many patterns of Imperial ship, with their grandest achievement being the production of the Oberon-Class battleship. Though production of those mighty ships is a massive endeavor and can take many decades to produce a single one at the expense of the production of other lesser craft. 

'''Hephaestus-IX''' is an industrial world dedicated to the production of cybernetics, robot parts and war vehicles. Especially the Castellax patterns of robots. The world also produces several varients of Leman Russ Battle Tank. Despite its vastly built up infrastructure, the world is denied Forge World status by Mars due to an edict by a Forge-Master Primus past and is a source of major contention between the inner and outer worlds.

'''Haphaestus-X''' is a repository world covered in temples to the Omnissiah and to the God-Emperor of Mankind known for its vast cogitator banks containing technological information dating back to the great crusade, notably the construction and maintenance of photon weaponry and patterns of plasma weaponry rarely seen in the imperium. This world is kept warm by ancient climate engines which maintain the atmosphere of the planet and keep it habitable. What is not covered in temples is covered by manufactoria which run constantly to build the highly effective Hephaestus pattern-Godsbane Lance Battery. A powerful photonic weapon mounted on main battleships which continues to be in high demand. A quarter of the world lies in ruin from an Ork Whaag! attack, partial restoration of the lost data is proceeding slowly.

'''Hephaestus XI and XII''' are gaseous planets rich in hydrogen, nitrogen, and various other gasses. In orbit around these planets are vast space-borne mining platforms which continuously plumb the depths for the precious elements. On the moons of Hephaestus IX exist manufacturing facilities for voidcraft parts. The mined gasses are used in the construction of plasma reactors.
