From the introduction: Eurasia After the Bomb ... Mutants in Xanadu is different from all other books in the After the Bomb series in that it contains magical characters in addition to mutant animals. The Nobles, a group of humanoid unicorns, dragons, griffons, and other mythical beasts rule both of the main countries in this setting. User summary: This fan-made expansion uses intellectual property and esp. artwork in violation of copyright. V. M. Wyman is attributed but was probably uninvolved in the creation/organization of the material. This sourcebook requires the use of Mutants in Avalon.
