Here's their take on it:
Today on Barking Irons you can find the first micro scenario of the new Terminus campaign for USE ME Science Fiction by the game's author, Gavin Syme.
Terminus. Invisible and impermeable, until a civilisation reaches a certain point of technologial advancement: the ability to reach it's solar system's edge. It is only then that Terminus appears.
In the first adventure the Challengers, having landed on Terminus, struggle to defend thier stricken vessel from the onslaught of unknown enemies.
