(former Paradise World/Agri World)
Iax, also known as the "Garden of Ultramar", is a planet in the stellar realm of Ultramar.
Iax was an Agri World whose climate and fertility has made it one of the most productive worlds in the Imperium. There were no large cities on Iax, its land given over to producing quality food. The oldest and most urbanised area is the ancient fortress city of First Landing, its tall citadel withstanding the barrages of invaders over the centuries.
During the Plague Wars, Iax became the site of major fighting. A group of Imperial Guard refugees brought to Iax were revealed to be unwitting Daemonic vessels, transforming them into Plaguebearers who managed to summon a cohort of Great Unclean Ones under Ku'gath. The Daemons summoned vast armies which ravaged the planet. Later, Roboute Guilliman and Mortarion engaged in a fateful duel on the planet. The Death Guard eventually escaped under cover of a Virus Bomb. It is now a Death World.
