The Tyrant Star, also known as Komus, is an uncategorised stellar anomaly found in the Calixis Sector of the Segmentum Obscurus. Komus appears as a black dwarf star whose arrival in the sky of a world is seen as an imminent herald of catastrophe, while the existence of the Tyrant Star is itself part of a wider prophecy called the Hereticus Tenebrae that is of great interest to the Imperial Inquisition. Unraveling this prophecy and the role of the Tyrant Star may be crucial to preventing a cataclysm that will consume not only the worlds of the Calixis Sector but perhaps the entire Imperium of Man.

The Tyrant Star and the Current Campaign

Inquisitor Sand is not interested in the Tyrant Star, but one of his Acolyte Cells: Red Cell had the horror to witness its manifestation twice- once during a a celebration on the planet of Quaddis called the “Festival of Tattered Fates” and once over the planet of Dusk with the release of Eramus Haarlock from its hold. Both times its unholy light caused planetwide madness and death. Its appearance appears related to the legacy of the infamous Rogue Trader Erasmus Haarlock and it was later revealed that the Tyrant Star is under the control of Eramus Haarlock- though whether the Star controls Haarlock or vice versa remains to be seen. With Eramus Haarlock now roaming the galaxy after being freed by Inquisitor Herrod and Red Cell the fate of the Sector and beyond remains in question.
