Cradle of the Moon (月の揺りかご, Tsuki no Yurikago?) is an unfinished 13 chapter long side-story, set after the main events of the Alicization Arc in the Web Novel. Reki last updated this story on December 6, 2009.
It is now some time after the events of Volume 15 and Underworld has entered a state of peace. The people of the Human Empire, the people of the Dark Territory, the Goblins, Orcs, Ogres, and Giants have all signed a peace treaty and the Dark Territory and the Human Empire have opened up for trade. After the War of the East Gate and Rebellion of the Four Empires, the four Imperial Noble Families, who had been oppressing the common people, had finally been overthrown. The Underworld Fundamental Law has been introduced and the Taboo Index has been revised. In a few years, the Integrity Knights will become the largest fighting force in all of Underworld. Among them will be Ronye and Tiese (and their dragons, Tsukigake and Shimosaki), who are currently Integrity Knight Apprentices.
- Reki states on his site, that Cradle of the Moon is designed to be a standalone Fantasy Story, which happens to have characters with the same name as those from SAO.
