The Fisher King's species

The Fisher King was the king of an unknown species.

History
Following his apparent death, he was transported to Earth by a Tivolian named Albar Prentis. He was actually in stasis and killed Albar, who became a ghost-like transmitter that mouthed the words "the dark, the sword, the forsaken, the temple" these words were a broadcast to the rest of the species that told the location of the king's stasis chamber. The species was then supposed to invade Earth. He was stopped by The Doctor.
