"A death on Thule would be a marvellous thing."


After receiving an invitation to visit the frozen planet of Ultima Thule, Koenig, Helena, Bergman and Carter land on the surface and soon find themselves lost in a blizzard. Carter manages to make his way back to the Eagle while the others are rescued by the survivors of the Uranus Expeditionary Probe of 1986, believed to have been lost in a proton storm. The Alphans meet Dr. [Cabot Rowland] who reveals that his group have survived on Ultima Thule for 880 years and none has aged a single day! Now they are attempting to rebuild their damaged ship and Rowland fosters dreams of travelling the stars as an immortal god. He invites the Alphans to give up their lunar home and join them on Thule, but Koenig learns his terrible secret...
