Anathrax

Anathrax is a Daemon World in the Eye of Terror devoted to the Lord of Plagues, Nurgle. A lush but pestilant planet, it is covered by giant bulbous fungus made up of puffy-eyed heads that cough and sneeze a grey mucous which corrupts those who touch it. During the  Abyssal Crusade, the  Iron Drakes   Chapter  of Space Marines  was ambushed on the planet by its vile vegetation and  Plague Marines , resulting in their eventual corruption into the warband of  Chaos Space Marines  known as the  Grey Death. Another of The Judged Chapters on the Abyssal Crusade was also corrupted on Anathrax and renamed themselves the Talons of Anathrax.
