Alera MU
Codex Alera is a fantasy book series by Jim Butcher. The five books in the series so far chronicle the life of a young man named Tavi in the empire of Alera, on the world of Carna. Every Aleran of every rank and station, except for Tavi, has some degree of command over elemental forces or spirits called furies. The story takes place after the rise of a fictional empire similar to Rome where the First Lord must stave off in-fighting amongst the nobility of a now decadent empire, and hold the throne through sheer force of strength and will. Tavi, trapped by fate in the midst of conflicts at home and abroad, 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.
