Restac

Restac was a Silurian, and also a Commander in the Silurian military. Her twin sister Alaya kidnapped people from Earth's surface and locked them up, presumably for experimentation. This could be seen as some form of payback for the Humans drilling down (unknowingly) into their underground city. Restac was wholly adamant on provoking a war, so that she could reclaim the Earth from the Human Race. Angered when ordered by Malokeh (who was also a Commander in the military, but preferred his laboratory) to put down her weapon after threatening to execute the Doctor, Amy, Mo and Nazeem, she went on a revenge-driven rampage. Restac then went on to threaten the humans and even went as far as killing Malokeh. She was angered to discover that Ambrose had murdered her sister, Alaya, she then went on to drive the humans out, but Eldane, the Leader of the Silurian released a deadly gas, killing Restec. This is because that Restec had gone too far, and Eldane only wanted peace between the two races. With her last dying breath, she fired a shot at the Doctor, but Rory intervened, and took the blow.
