It's easy to miss, but the extent of Vizla's lethality and One-Man Army status is made evident by the fact that while the whole of Damocles' pension liabilities amounts to 29 million dollars spread over scores of retired assassins, 8 of those millions correspond to Vizla's personal fund. And the assassins are paid per hit, not a salary. Meaning that Vizla was responsible for almost a third of all of Damocles business, all by himself.
