The story initially deals with the character of Jonathan Thomas Meriweather, referred to by the locals as, Jon-Tom, when he is unwillingly pulled into a fantasy world by the turtle wizard Clothahump. Having been, at the moment of his transportation, high on Cannabis, Jon-Tom initially thinks it is all a dream brought on by the drugs he has been using. He soon finds out differently and that he is in an unfamiliar world with little prospect of returning home anytime soon.
The world of Spellsinger is largely inhabited by animals that are similar to those found on Earth, but are anthropomorphic: generally bipedal, they are intelligent, able to wear clothing and handle tools, generally closer to human-sized than their Earth counterparts, and are capable of speech. Humans, far from being the dominant species, here are equal to others.
