This story started out as first contact between the Twelve Colonies of Kobol and an alien civilization when Starbuck is rescued by an alien ship after chasing a Cylon heavy raider in the orbit of a gas giant. I decided to take the story into a completely new direction and it has evolved into something a lot more complex, now containing multiple crossovers.
