are revealed to be criminals deliberately imprisoned there as punishment. Also, The Bride of Peladon saw the Fifth Doctor, Peri and Erimem encountering an Ice Warrior on Peladon, the Ice Warrior investigating the recent death of his sister on Peladon, culminating in him sacrificing his life to trap the Osiran responsible for his sister's death. The Ice Warriors made an appearance in the Bernice Summerfield audio The Dance of the Dead, and the new gardener on the Braxiatel Collection is an Ice Warrior named Hass. The Fifth Doctor meets the Ice Warriors yet again in the audio play The Judgement of Isskar. This serves as a sort of origin story for them. The Doctor lands on Mars, looking for a segment of the Key to Time. At this point, Martians are a peaceful communal community who do not even know the meaning of the word "warrior". But, when the segment is taken away, the Martian atmosphere slowly erodes. They become desperate scavengers and, eventually, Ice Warriors. In the 2010 Deimos / The Resurrection of Mars, it is explained that many Ice Warriors went into cryogenic suspension after Mars was rendered inhospitable. Some of these vaults were on the Martian moon Deimos and others were in the Asteroid Belt. Centuries later, some of these Ice Warriors were revived and eventually discovered a new home world. The planet was a beautiful, civilized utopia called Halcyon. The Ice Warriors killed all of the twenty billion inhabitants and renamed it New Mars. The Doctor's old foe the Monk attempts to wake the Martians up centuries in advance so that they can re-colonise Mars at the cost of the human colonists on the planet at this time, arguing to the Doctor that this will save the inhabitants of Halcyon later. The Doctor prevents this plan to preserve history, but the Monk uses this scheme to manipulate the Doctor's current companion Tamsin to join him (not revealing to Tamsin that he was the reason the Ice Warriors woke up in the first place). In Lords of the Red Planet, the Second Doctor encounters the Ice Warriors at an early point of their history. This, along with The Judgment of Isskar, serves as an origin story for the Ice Warriors, with Lords essentially depicting their genetic origin while Judgement depicted their cultural growth. This story is from an unproduced script of Patrick Troughton's final season as the
