Eldane

Eldane was the leader of the Silurians in a colony beneath Cwmtaff, Wales.

Biography
Eldane was awakened by Malokeh when Restac was attempting to execute the Doctor, Amy Pond, Mo Northover and Nasreen Chaudhry. He put a stop to the execution and had discussions with Amy and Nasreen about the future of their species. When Restac struck back, he escaped with the humans and the Doctor and went back to the Silurian lab where he attempted to decontaminate Tony Mack, but didn't have time. He then set the chambers to be filled with poison gas which would make the Silurians go back into stasis to avoid it, to allow time for the Doctor and the humans to escape. He, along with Tony, Nasreen and all of the Silurians went into a thousand year sleep. (DW: Cold Blood)
