to leave. He records a poignant message for any future travellers that might land on the wandering Moon, giving a brief history of their voyage and their uncertain fate. He departs, bidding Alpha a heartfelt farewell. On the planet, Helena tries to decipher her captors' abstractions. Though confined in the column, they insist she is not a prisoner...free to go where her mind can lead her. Impassive as ever, they inform her of Koenig's bid to rescue her and win living space on this planet. When she asks if he will succeed, the male's enigmatic reply is that Koenig is very much afraid of their stopping him. Approaching the planet, the Eagle encounters an energy barrier. Koenig forges on, but the Eagle cannot withstand the powerful force-field. The two men eject as the ship breaks up. Floating in space, Koenig calls out to Carter—but the astronaut is dead, his space-helmet visor shattered in the explosion. The aliens begin indoctrinating Helena to their world. The complex around her is a macro-brain, developing and growing with each generation of attendants who reside within and fed by the life-force of the collective population.

In bringing him back, his fear would also return—fear which will destroy them all. 'We are what we are,' she affirms, and Koenig plummets toward the planet.

As they exchange a loving glance, the destruction continues until the entire planet is laid waste. Now faced with certain defeat, Koenig contacts the approaching Eagles and tells them to turn back. As they are going to die,
