Codex Alera is a fantasy book series by Jim Butcher. The series chronicles the coming-of-age of a young man named Tavi in the realm of Alera, an empire similar to Rome, on the world of Carna. Every Aleran has some degree of command over elemental forces or spirits called furies, save for Tavi, who is considered unusual for his lack of one. As the aging First Lord struggles to maintain his hold on a realm on the brink of civil war, Tavi must use all of his intelligence to save Alera.

Alera inhabits most of a large continent that is inhabited by the Icemen to the north. They are connected to another large continent held by the Marat via a land bridge, which is the location of the Calderon Valley. The Canim reside across the ocean to the west, staging regular, bloody raids on coastal settlements. A map of the realm, illustrated by fan Priscilla Spencer, was published in First Lord's Fury.

The inspiration for the series came from a bet Jim was challenged to by a member of the Delray Online Writer’s Workshop. The challenger bet that Jim could not write a good story based on a lame idea, and Jim countered that he could do it using two lame ideas of the challenger’s choosing. The “lame” ideas given were “Lost Roman Legion", and “Pokémon”.

Furies are elemental spirits (earth, water, fire, wind, metal, and wood) that inhabit all aspects of Alera. Some are small and cannot be seen, and others are powerful enough to manifest when called upon by their wielders. There also exist "Great Furies," the most powerful and ancient of these spirits, by which Alerans swear and curse. They manifest as geographic formations of great elemental power, such as volcanoes and oceans, and are far more often restrained or provoked than explicitly commanded, and then only by fury-crafters of exceptional strength. Many Alerans are unaware of the Great Furies' actual existence, imagining them to be more mythic than real, but this disbelief is incorrect.

Tavi has not been a contender in any CBUB matches.
