The Zools are a humanoid species whose homeworld was destroyed thousands of years ago and which make up the staff of the huge multi-species space station complex known as Point Central. They are completely mute and very reserved, but are known for their honesty and efficiency.
The Zools are usually the only species to be found moving along in the station's corridors, as the delegates from each species are typically confined to their own environmental cells and only interact with each other using the communication screens. As the Zools are oxygen breathers, the corridors are thus inhabitable for Humans, though.
