Barbarus was the homeworld of the Death Guard prior to the Horus Heresy. It was the planet on which Mortarion landed; its atmospheric quality was so poor that even Mortarion could not breathe at the top of its mountains.
Barbarus was a Feral World which orbited near its dim yellow sun. The atmosphere was thick with virulent gases and a constant fog was spread across the planet. This made it a very dark, dismal place of night with short, shadowy days. Only below the fog could humans survive, in the valleys and low plains. At some point, the planet fell under the domination of the Overlords, cruel Xenos species. Able to resist Barbarus' poisons, the Overlords survived within the toxic cloud and built great grey keeps in the mountains. The Overlords began to use the humans as slaves and spread terror among them. After landing on the world, Mortarion eventually led the citizens of Barbarus in a revolt against the mountain ruler, toppling them before joining with the Emperor.[Needs Citation]
After the Horus Heresy and the commencement of the Great Scouring, the loyalists subjected all worlds associated with the Traitor Legions to Exterminatus. Barbarus was among the worlds destroyed by the vengeful Imperium with Virus Bombs. Another source states that it was destroyed by the Dark Angels shortly before the Siege of Terra with Cyclonic Torpedoes. Yet another source states that Barbarus was invaded by Imperial forces shortly before the Siege of Terra before its destruction.[Conflicting Sources]
In the novel The Lords of Silence it is stated that Barbarus was destroyed after the Horus Heresy with virus bombs. However the novella Dreadwing states that it was destroyed by the Dark Angels shortly before the Siege of Terra with Cyclonic Torpedoes. In White Dwarf 478, the Siege of Barbarus is depicted as a large land battle that takes place before the planet is destroyed.
