Deimos was the fifth story in the fourth series of the Eighth Doctor Adventures, produced by Big Finish Productions. It was written by Jonathan Morris and featured Paul McGann as the Eighth Doctor and Niky Wardley as Tamsin Drew.

The story continued in The Resurrection of Mars.

Publisher's summary[]

Millions of years ago, the noble Ice Warriors fled to Deimos, moon of Mars, hoping to sit out the radioactive death throes of their home planet. When the TARDIS lands on Deimos, the Doctor discovers that the Warriors' ancient catacombs are now a popular stop for space tourists.

But the Martian dynasties are more than history, and the Warriors are far from extinct. It's not for nothing that "Deimos" is the ancient word for "dread"...

  • The Ice Lord Izdaal was the greatest Ice Warrior who ever lived in Martian society. His studies determined that Mars' atmosphere was no longer capable of keeping out radiation from space. This would eventually kill them all. He told the government that their turmoil was not over and with the evidence of sickening children, he declared that their world was no longer sustainable. He was ignored by his people. Lord Izdaal made the ultimate sacrifice. To prove himself right, he elected to step outside and face the Red Dawn, knowing he would die. His death led to his people coming to the same conclusion and they worked to survive, slowly becoming a conqueror race that took what they wanted from others. (AUDIO: Red Dawn)
