Tallin Aleth, Kabalite Trueborn from the Kabal of the Lords of Iron Thorn (http://warhammer40k.wikia.com/wiki/Kabal_of_the_Lords_of_the_Iron_Thorn).  Tallin fled through the Webway after the Kabal was laid low by Absdrubael Vect and his Kabal of the Black Heart.  Vect created a slaughter that was to a scale that was unseen for such a murderous and bloodthirsty race that many within the Lords of Iron Thorn attempted to escape while they could.  Tallin was one who did flee after the Kabal started to destabilize with the loss of Archon Draylin Qu due to the betrayal of his own daughter Veryna who was a consort to Vect.  Tallin did not witness the events, but caught wind of the betrayal.  Knowing that others will begin to flee once word slipped of Qu's death, decided to leave before walls could close in fully around her.  She was angry at such a betrayal.<br/><br/>The Lords of Iron Thorn were to become one of the first to finally break free of Vect's influence, and if people had been loyal at least until they could force Vect's hand to stand down then they could have started to go back to their basic instincts once their realm was settled in.  Since no one could just resist the short-term power plays that would lead to their failures for just a little longer, she herself felt no loyalty to fight on.<br/><br/>So she fled like a coward into the depths of Webway, doing her best to elude whatever hunting parties were after her since she was still a Trueborn and valuable.<br/><br/>Deeper and deeper into the depths of the Webway since went, doing her best to sate the thirst Slaanesh had on her soul as her body wracked from the soul draining malignancy her kind had.<br/><br/>She eventually found an exit from the Webway which took her to the Koronus Expanse on a world where a Rogue Trader was at.  This Mon-Keigh had power, great power within their Imperium and knew that she could hide aboard his vessel from her hunters while she licked her wounds and grew stronger.  There was the catch though, and it meant sullying her own hands to work for this Mon-Keigh as sneaking aboard was off the table, there were too many eyes aboard a Mon-Keigh vessel that she would get caught.  So instead she investigated herself about who this Rogue Trader was and whether he was a viable option to work for as a means to make herself stronger.
