Grell

The Grells are a humaniod species that appear in The Outer Limits.

Biology
The Grells have mottled yellow skin, and are able to see ultraviolet light by day and heat at night.

History
The Grells were rescued from their dry and dying planet by humans, unfortunately this humanity had long since forgotten the horrible role of slavery on their world, and forsaking their morality turned the Grell into slaves on Earth. The aliens wronged by humanity rebelled against their false-saviors, fighting a guerrilla war against the human government.

Culture
The Grells believe in the sanctity of a proper burial, a right that was taken from them by their cruel human masters. Due to the human restrictions they haven been forbidden to write or read. Despite the repression, they have a unique art called Grell alchemy that can in some cases heal serious wounds and even convert a human into a Grell.
