Sorna Losu is one of the most accomplished assassins in the Acta Sanctorum and has never failed to kill her target. She generally only takes on jobs that center around people who are thought to be extremely difficult to kill or extremely difficult to find (even for the Sanctorum). Sorna is patient and very skilled in the art of deception, tending to let her victims trust her so she can eventually dispose of them at a time and place of her choosing. For this reason, her true name and identity are virtually unknown outside of the Acta Sanctorum.
