Hubwards is a d20 Modern/Future campaign set in and around the space station known as the Hub. The size of a city, the Hub floats between the orbits of Saturn and Uranus. It is almost the largest station in the Sol system, narrowly outsized by some in and around the orbits of Earth and Mars. A handful of slightly smaller stations also cluster about the FTL Jumpgate, past the orbit of Pluto.
The Hub has had a large historical impact upon mankind and the Sol System, as it was the site of first contact with an Alien race – the Fraal.
