Doctor Who Entropy Plague Audio Cd

"A Great Darkness is spreading over E-Space. Entropy increases. In search of a last exit to anywhere, the TARDIS arrives on the power-less planet of Apollyon, where the scientist Pallister guards the only way out - a mysterious portal.

But they're not the only menace on Apollyon. The Sandmen are coming, creatures that live on the life force; that live on death!"
