The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the Native Americans in 1492. Over the horizon came ships of a technologically advanced, aggressive culture, and BAM! There went the good old days, when humans got killed only by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

Udo's biggest problem isn't being a digger (that's low class), or staying drunk (that's damn expensive), or avoiding the Dwergaz (they're monsters), or even pissing off the supposed Gods.

A hunger that has swallowed half the universe. They don’t care which planet we live on. They want to end us all. But where there is life, there is hope. And where there is hope, there are heroes. This time, vengeance will be ours.
