Merrapine Scar
From Tardis Wiki, the free Doctor Who reference
The Merrapine Scar was a strange phenomenon, rumoured by some Alliance scientists to permeate the barriers of time.
It was located on the Laputa system, above Guilliver's Rest, the only planet in that system. Not much was known about the Scar, because the inhabitants of Gulliver's blocked all attempts at studying it. However, it was rumoured that they used the Scar's energies for mysterious research projects. (PROSE: Cyberon)
