Kasteroborous

Kasteroborous was a galaxy.

In the Alpha and Beta Quadrants of the Milky Way Galaxy, there were legends of a civilization in the Kasteroborous galaxy that developed and mastered time travel. However, they found the risks of time traveling and interfering in the time-lines to be so unpredictable and dangerous that they never dared do anything at all, and stagnated.


 * With a slight difference in spelling, and a change from constellation to galaxy, this is a reference to the Kasterborous constellation in Doctor Who, the location of the planet Gallifrey, the homeworld of the Time Lords who have a very similar history. The unnamed time traveler identified as the Doctor may therefore come from the Kasteroborous galaxy.
