Moon Kingdom

A radiant civilization lost to time, yet its light still guides the guardians today.

The Moon Kingdom, often referred to as the Silver Millennium, was a utopian civilization located on Earth's moon. It served as the home of the Sailor Guardians and the royal family before its destruction. This ancient society is central to the reincarnation cycle that drives the main narrative, connecting Usagi Tsukino directly to Princess Serenity.
