Ohrbi

The Ohrbi (singular: Ohrb) are a race of sentient chalcopyrite spheres which glow in ultraviolet about the size of a lawn orb, from an unreal space. They have mind control abylities that are deflected with diamond. Five fell to earth in 1507, nearly enslaving the entirety of Australia, before being deffeted in an Aboriginy revolt. They can however be tamed with the Glyph "Peace" into imoble pets who follow your instructions, with their mind control powers intact.
