The Tellius Series are the games of the Fire Emblem series featuring the continent of Tellius, namely Fire Emblem: Path of Radiance for the Nintendo GameCube and its sequel, Fire Emblem: Radiant Dawn for the Nintendo Wii. Most Fire Emblem content in Super Smash Bros. Brawl originated from the Tellius Series, due to that content being marketed most recently at the time of release.
In the Tellius Series, there are two races; the Beorc and the Laguz. The Beorc fight with ordinary weapons; Swords, Axes, Lances, Bows, Magic, etc. The Laguz fight in animal form, and use Claws, Beaks, Fangs, Talons and Breath. There are some in the world of Tellius who are Branded; the branded are Beorc with Laguz blood flowing through their bodies.
Although the Tellius Series games were fairly well received by reviewers worldwide and fans overseas, in Japan it was found to be the least popular of the Fire Emblem settings; multiple sales tracking sources confirm that both games struggled to break 150,000 unit sales during their respective print runs in Japan. Many characters from the setting, including Ike, tend to fare poorly in character ranking polls in Japan as well.
