The story follows the lives of various mythical creatures, such as a gryphon, a nixie, a satyr, and a sphinx, as they disguise themselves (using magical medallions) into the world of humans. Its narrative, so far in one completed arc and one in-progress arc, presents the point of view of Michelle, a college-aged Sphinx who has only recently learned that she is not a human, and the various points of view of the citizens of Liverpool's Avalon, an entire magically-hidden city. The plot often works to establish a theme of different versions of normalcy, promoting acceptance and diversity.
