A large, spacious chamber at the north end of the Common Fields, it's sheltered from the rain and filled with heated sand for the eggs. Also lined with stands where spectators can sit to watch hatchings. A large gold's clutch or several smaller clutches can fit on the sands at one time; though these days the sands are occupied almost constantly by one or more reds. During hatchings, a table with rags and buckets of meat is set up on the sands for newly-Impressed riders to clean and feed their new bond-mates.
