Jupiter is the sixth planet in the Sol System and homeworld to the species known as Jupiterians. It was once a thriving world of civilisation and development beneath the blanket of gaseous clouds in its atmosphere. The god Marduck presided over the world and was a danger to the native Jupiterians. The planet was destroyed by accident by the human named The Otter and was transformed into a second sun, dubbed Xenos. After a meeting of the G8 on the Cosmic Nullius, it was decided to render the sun inert again and save the solar system from destruction.
