You were tried, or maybe you weren't; the courts are crowded and the amendments not as strict as they once were. You were sentenced to death. Your sentence was commuted to transportation.
It's a long ride between the stars, and it kills one in four of those who try it--but of course when you're dead already it's not much of a risk. You lost bone density and muscle tone, and they made you dance with electricity so you'd walk again someday. You lived. You crawled onto the dirt of an alien world.
It's blue.
All the light, everywhere, is blue.
