Kabalite Sirens

The Kabalite Sirens are a warband of xenos exiles roaming realspace, selling their blades to anyone who can afford them. They are believed  to reside in underhives and work through intermediaries to subsist in Imperial space.

Creation
The Kabalite Sirens were created more by accident than intent. During the Wake of Vect, several kabalites meant to be present in the overlord's trap were absent due to an unrelated interkabal conspiracy crafted by Ishara Cull. In the aftermath it was believed they were plotting against Vect, somehow caught wind of his plans and were marked in the Dark City. The women quickly grabbed what they could and fled into Real Space. Ishara Cull managed to contact several humans with whom she had established friendly relationships during her time serving on a Rogue Trader's ship. They became live-in assassins of sorts for a planetary governor, a secret weapon until an inspection fleet forced them to flee yet again.

When they returned to the stars, Ishara's network gave them a foundation as something of a mercenary company.

Members
Ishara Cull, The Twilight Goddess: Former Scourge of the Black Heart

Ishara Cull has used her innate  cunning, brutality and experience to maintain her rule over the Kabalite Sirens. Her knowledge and connections in Realspace keep her from being easily replaced.

Kylos Ethrek, The Corpse Bride: Former warrior of the Last Hatred

Living proof that the haemonculi of Commorragh can resurrect a slain warrior from fragments of bone and strips of flesh, as well as a testament to their ability to do it more than once. Kylos holds a love for death and the dead that would turn the stomachs of Realspace humans.

Kheraes Xesh, The Temptress: Former warrior of the Poisoned Tongue

Eager to live up to her Kabal's reputation, Xesh is a mistress of lies, plots, deciet and conspiracies alike. While she has proven unable to out-scheme Cull, she has settled for sportingly wrongfooting her prey at every turn.

Veth’va Maestros, The Heartless Queen: Former Sybarite of the Black Heart

Trueborn daughter of Kabal leadership, Maestros shows an arrogance and love for battle rivalled only by Ishara Cull. Due to their similar appearance, many believe that Veth'va was a commissioned clone of Ishara so that she might have a lover as beautiful and clever as her. These rumors are quickly denied by Maestros though Cull insists there is some truth to them in order to get under her skin. She is often seen as Ishara's second in command, even leading operations if Cull herself is unable for various reasons.

Exelot Vorn, The Fleeting Lust: Former warrior of the Flayed Skull

Screaming across Realspace  warzones on raider crafts was a favorite passtime for Vorn, a vice Cull easily exploited  to earn her temporary loyalty. Now while stuck in exile she's found her best and only hope for survival is as Cull's defactor shock trooper and speartip of any open offensive operation.

Vivithrax Vhrex, The Domineering Mistress: Former warrior of the Obsidian Rose

One of many perfectionists in the Obsidian Rose, Vivithrax was already in danger by the time Ishara found her. The mother of a trueborn son, her son quickly turned against her and demanded her death. Cull saved her life in exchange for her service as the mistress of arms and armor for their warband. At first their exile was an existential crisis, though she began to  relish the challenge of maintainig their equipment with the materials availible in Realspace.

Methods of Operation
The Kabalite Sirens are a largely clandestine organization. They attempt to pass as humans or mutants where possible and maintain a system of human intermediarries to make their living as easy as possible. Ishara Cull knows several governers who could allow them to stay in their spires, however more often must instruct the sirens on how to lay low in underhives, frontier worlds and massive voidfaring fleet communities. She often works up a ladder of normallity, mutants talking to less horrid mutants who talk to mutant tolerating humans who talk to more conservative humans and all the way up to whoever has what they need. They will rarely if ever expose themselves as xenos unless they must, and would  prefer to complete a contract and  leave with even their clients knowing as little as possible.

+ M.42.017 Lord Helmawr contracts the Kabalite Sirens to deal with rumors of a growing Slaaneshi cult in the depths of the Underhive. They discovered the cult was performing daemonette summonings and had built up power in the underhive of Primus; The Sirens were not merciful enough to kill a single one and their screams can still be heard howling down the tunnels from automatic suffering caskets that none seem able to locate. Its believed that the coffins themselves were concealed in the walls and floors and the plating was unable to muffle their sounds of agony.
