Professor Karst was a Russian scientist assisting General Vostok in his plan to overthrow the Russian president. He hoped to control the golem they had found, but instead Vostok took control of the golem himself and ordered it to kill Harst, and the Quests. The golem threw a boulder at them, causing a cave-in that buried Karst as he tried to run. He survived and later returned, and attempted to fight Vostok for control of the golem. The golem knocked a section of the ceiling onto Karst, crushing him.
