Titan III

Titan III was a desolate planet which was home to a safehouse used by Azmael after abducting Romulus and Remus Sylvest. Hugo Lang, who had been pursuing them, was shot down over the planet and crashed there. He was rescued by the Doctor, who had come to Titan III to atone for almost killing Peri Brown by becoming a hermit there. The three of them were captured by Azmael and imprisoned, but unknown to him, Noma had set the base to self-destruct. The Doctor and his friend escaped and pursued Azmael to Jaconda.
