Scourge from the Dark

The Scourge from the Dark is the name of the Imperial defensive campaign conducted by the Mourning Wardens in defence of the Occiana System from the constant attacks by the notorious xenos raiders known as the Drukhari.

Background
The systems near Occiana are overrun by dozens of Kabals and other Drukhari forces, which descends on the inhabitants to bring them back to their cursed realm. The Ninth Defender, Elbrad de Castelrous, defying orders to remain stationed with the 8th Company on their homeworld, bring his forces against the xenos. In a series of battles which all end in his favor, with minimum losses, he send them back to Commorragh. While his Company deal with the raiders, the rest of the Chapter is free to deal with other threats -and more than one Battle-Brother start to talk about a de Castelrous gaining back the rank of First Defender thanks to his success, to the chagrin of Caïus Ignatius Juvii, the current leader of the First Company.
