Gadmeer

The Gadmeer are a fictional race on the television series Stargate SG-1.

The Gadmeer existed for thousands of years, before being wiped out. They created a ship for the purpose of terraforming a new planet for them. For ten thousand years it travelled around the universe looking for an viable world to terraform. Their sulfur environment was a problem in the episode "Scorched Earth" when the ship attempted to terraform a planet being used at the time. The ship created Lotan (Stargate-SG-1) to communicate with the settlers and inform them they had to leave.
