The Serpent (The Seventh Galaxy)
From Tardis Wiki, the free Doctor Who reference
The Serpent was a chain of thirteen stars which moved through the Seventh Galaxy without a pattern, never retracing their steps. They travelled at a speed slightly below the speed of light.
At least sometimes, the visible side of Skaro faced the region of the Galaxy containing the Serpent. (PROSE: The Seventh Galaxy [+]Loading...["The Seventh Galaxy (feature)"])
