Valley of the Moon

The Valley of the Moon was a place in the Southern Crystal, close to the border of the Ruby. It was located right between two tall mountains and was covered in a lush, green forest, except for right in the middle of the valley - there you would find a clearing that, when the moon was out, had grass that shone like silver.

The Valley of the Moon was never inhabited, but upon moving their family to the Crystal, the Weasleys owned a house not far from it and Mandy Diamond, both their daughter-in-law and the Queen, had placed the Valley under the Weasley's ownership. Molly Weasley was famous for throwing dinner-parties in the valley, inviting people from all over the Four Nations to join them.

Time of Ice/Third Moriquendi War
The Valley was abandoned when Andernilwen took control and was said to be haunted by the ghosts of the "extinct Weasleys". This was merely a safety spell to protect the Valley from the Moriquendi; all of the Weasleys had survived and could be found down at Hogwarts II later on. When Andernilwen was killed, Lilith Roberts gave the Valley to the Weasley's once again. They accepted it but decided to live at Hogwarts, except from when it was time for another dinner-party.
