Sskel, with Azaxyr and the other Ice Warriors, were hiding in the refinery on Peladon, and Sarah caught a blurred glimpse of Sskel until the lights were turned off. When the Third Doctor and Gebek discovered Sskel and other Ice Warriors, they took over Peladon and placed it under martial law. Sskel told Azaxyr that hostages had been taken, and would be killed in selected numbers if Azaxyr's commands were not obeyed. When Ettis and a group of miners burst into the throne room to rescue Gebek, Sskel and the other Ice Warriors shot down everyone of the miners except Ettis who managed to escape.
