|Class:||Unknown, former Xenos World|
Arkenath is an Imperium world, that was once home to a Xenos species known as the Vektates. They were a deviant culture and had the ability to form an overmind, which they used to enslave Arkenath's Human population. The Vektates were ultimately destroyed during the Great Crusade, after the Ultramarines Captain Hektor launched a campaign to free the enslaved Humans. When the last of the Vektates were killed, the Humans of Arkenath were freed of their mind control and eagerly joined the Imperium.
