The Savage Sword of Conan #199

Black Zarono has betrayed the Barachan Isles to the Zingaran Navy. Conan and a mere handful of pirates fail to defend the Port Torage from these savage invaders. Lord Hambria (the husband of Lady Morganis) demands that Conan lead him to an underwater temple so that his magician Sinnjatorix can usurp the power of the monster Atarata. However, Sinnjatorix cannot control the power and is turned into a monster himself who slays Lord Hambria. Conan kills Sinnjatorix and is then rescued by some Barachan pirates.
