Doctor Ivanov was a scientist working for the Human Empire under the command of Admiral Nyborg. He and his co-worker, Jen Komati, were transported to the surface of Avalon to investigate the machinery malfunctions. However, they were embroiled with the locals in finding Merlin's Helm. While searching on the Shadow Isles, he and Captain Shannon entered Prydwen and found the helm themselves. When putting the helmet on his head, the power was too overwhelming and so he was killed.
