Written by Mark Gatiss
An ancient reptilian race. They built themselves a sort of bio-mechanical armour for protection. The creature within is at one with its carapace. The Ice Warriors. They could build a city under the sand, yet drench the snows of Mars with innocent blood. They could slaughter whole civilisations, yet weep at the crushing of a flower.
