**First Appearance:** #book10 One of the seven inhabited worlds in the [[Tau Ceti]] system. It is one of the smaller, more sparsely populated ones—primarily a manufacturing world, hosting most of the more polluting sorts of industries, like chemical production, fuel synthesis, metallurgical and mineral processing, and heavy fabrication. It was a way of keeping all of the most harmful material in one place rather than spreading it across an array of worlds. The result, unfortunately, is a single planet that was badly polluted, meaning much of it was run by AIs. Human workers lived in orbitals and commuted down to the surface.
