The Madrian Empire rules worlds as numerous as the grains of sand on a beach. When the Madrians conquered Roby's homeworld, they brought him to this godforsaken lump of a world, to toil at their will.
Now the Gate has failed, leaving them without communications or transport to the rest of the Empire. When Roby identifies the problem, he's offered a chance to fix it.
Roby now faces a quandry. Even if he can repair the damage, should he? Will he be better off reunited with the masters' metropole? Or will he only complicate a difficult life?
