Ka'jagga'nath

Ka'jagga'nath is a Bloodthirster, a Greater Daemon of the Blood God Khorne.

History
In the Basilica of St. Mariel on the Imperial world of Van Horne an ancient prison is accidentally damaged during renovations. This forgotten stasis-reliquary contained the spirit of the infamous Bloodthirster Ka'jagga'nath, Lord of the Bloodtide. Breaking free of his imprisonment, the Greater Daemon unleashes a tide of gore, which washes through the basilica, corrupting everything and everyone it touches. The Emperor's most virtuous servants soon become afflicted with the murderous gall-fever that renders them into homicidal maniacs. They roam the nearby streets abducting hapless innocents and sacrifice them upon a desecrated alter of blood. In an orgy of destruction that lasts 8 days and nights, the ensuing carnage attracts more and more Daemons through to the material universe. Within only a matter of days, the Bloodtide will corrupt the entirety of the planet. On the morning of the ninth day, the Adepta Sororitas Order of the Ebon Chalice assault the basilica, resulting in some of the Battle-Sisters being corrupted by the malefic Bloodtide. The survivors endure valiantly but are soon slaughtered by a horde of Bloodletters atop the basilica walls. The Bloodtide is only abated with the arrival of the Grey Knights' 4th Brotherhood on Van Horne.

Turning their blades upon the tainted Battle-Sisters, the Grey Knights sate their blades in their innocent blood, effectively turning their weapons and armour into talismans of purity. The Grey Knights are then shielded from the goreflood of the Bloodtide and are able to make their way into the heart of the cursed basilica. Led by a trio of their Chapter's power Librarians, the Grey Knights find the Greater Daemon at the building's rotten heart. Ka'jagga'nath is only defeated by the valiant sacrifice of the 4th Brotherhood's Champion, Ordan. Before the Bloodthirster's spirit can escape it's broken body, the Grey Knights cast its foul soul back into the Empyrean drawing forth and banishing the Bloodtide and the summoned Daemons back with it, in a power psychic backwash.
