Alfava Metraxis

Alfava Metraxis was a planet which was orginally home to the temple of the Weeping Angels, but was later home to the Human Race after they terraformed it, so it was compatable for human needs.

When the Byzantium crash landed there the Doctor, Amy Pond and River Song went to the temple there to investigate and save the people on the Byzantium. (DW: The Time of Angels)
