Kabal of the Black Heart
The Kabal of the Black Heart is the largest Dark Eldar Kabal in Commorragh. Its Archon is Asdrubael Vect, who styles himself Supreme Lord of the Kabal of the Black Heart.
The Kabal was formed as part of Asdrubael Vect's plan to gain power over the Dark City, continuously raiding Imperial worlds in the Desedrian Gulf until attracting attention from the Salamanders Chapter in M35. Luring the strike cruiser Forgehammer into Commarragh, the aristocratic houses of Commorragh immediately claimed the strike cruiser and its cargo of Space Marines for themselves, unaware a Librarian had sent a warning to Nocturne. While the houses were trying to subdue the Marines, the Salamanders battle-barge Vulkan's Wrath, along with strike cruisers from the Howling Griffons and Silver Skulls, managed to get into Commorragh. They eventually freed the Forgehammer and returned to real space, but not before all but wiping out the old Aristocracy. With the ensuing power vacuum, the Kabal of the Black Heart managed to establish dominance over the Dark City with Vect installing himself as Supreme Overlord of Commorragh.
As of M41, the Kabal of the Black Heart has continued to maintain dominance of Commorragh for thousands of years, forcing a number of weaker Kabals to become vassals of the Black Heart, while fighting off ambitious rival Archons, some formed from remnants of the decimated aristocrats themselves.
