Amethyst

Amethyst is an uninhabitable planet in the Eora System. It is orbited by the moon Violet, which is home to the city New Violet. Amethyst is a corrupted dead planet, and due to close proximity gives New Violet a permanent violet haze. The radiation emitted from Amethyst is toxic to humans. New Violet has a controlled weather pattern of continuous rain, which is laced with a chemical that neutralises the effects of radiation from Amethyst.
