The Worlds of the Bound (WotB) are a creation of the author’s mind. In those xenofictional worlds, there are no humans, no Earth, and no Milky Way. Rather, the four space-faring worlds in this galaxy are populated by Iysh, Mengans, Aers, and Thurls.
Originally begun in 1999 as fan fiction for a popular science fiction television series, WotB has evolved into an internally consistent, epic tale that is an original work in its own right. It no longer has any association with any outside creations.
