Rhia Thyratia, or Dullahan as she is more famously known is an Inquisitorial Throne Agent in the Dark Heresy Campaign one of my best friends ran. She was a grim, snarky assassin skilled with the blade and firearms who never liked knowing the odds when it came to her chances of success, but with a sharp with and catlike agility she managed to pull off missions that were doomed to fail. Her time would soon be cut short after a botched assassination attempt on a corrupt Planetary Governor led to her capture, torture and eventual execution.
Fortunately her story didn't end there. She awakens in the arms of her savior, before the glow of a Rejuvenat Tank, large portions of her memory lost, including her skills that brought her far. She has since been reinstated as a Throne Agent, her skills and abilities growing as she takes on deadlier and more harrowing missions alongside her Inquisition Cell. She willingly undergoes cybernetic augmentation to dramatically increase her physical prowess. It is only recently that some memories of her time before her death had risen to the surface from her scarred subconscious.
This picture took FAR too long for me to finish, and were I a better artist I could have done the idea in my head justice.
