Neptune is an Imperial world of the Solar system, the system which holds Terra, capital of humanity.

History

An ancient world by Imperial standards, Neptune was first colonized by humanity during the Age of Terra.^[1] During the Age of Strife, the planet's inhabitants were mutated into hideous inhuman creatures.^[2]

During the early Great Crusade, the task of conquering Neptune and its moons as well as scouring its mutant hordes fell to the vicious IXth Legion. In the tunnels of Neptune's Moons, the IXth Legion fought a bloody war that saw 12,000 Battle-Brothers lost. Yet by the time Imperial reinforcements arrive, the Legion still endured and had succeeded in its mission. They had also replenished their numbers by recruiting among many of the dregs of Neptune.^[5]

By the Horus Heresy, Neptune's moons contained Human colonists.^[3] During the Solar War, Neptune and its habitats were ravaged by various Pirate and traitor Imperial Army vessels unleashed by Perturabo.^[6]

Notable Locations

• Laomedia - Moon. During the Horus Heresy Chaos Cultists unleashed toxic gas into its habits.^[6]
