This five-second voice clip has Illidan Stormrage saying “Now I am complete” in a deep, measured voice that lands hard on the final word. It feels tense and triumphant, like a villain savouring a dangerous change he has just survived. The line is from Warcraft III: Reign of Chaos (2002), spoken after Illidan consumes the Skull of Gul'dan and transforms into a demonic form.
