Eye of Orion

The Eye of Orion was a planet. It used to be a thriving holiday resort, but after the Last Great Time War struck it, it was converted into a shrine of the War, with only small memorial, nameless due to the many who died in the war. At this point, the only other structures were scattered ruins.

During its time as a shrine to the War, the Eye of Orion was still and quiet, covered in ruins, grass and mist. (Martha Jones's Myspace blog)

The planet is also known to be the most tranquil places in the universe. (The Five Doctors)
