For those of you who don't know much about Muarim or Fire Emblem: Path of Radiance, Muarim is what is known as a Laguz. (There's also a very racist term for his kind, but that's about as appropriate as the n word.) In his world, Laguz are treated as badly as african american people were in the 1930's, or how badly fish people are treated in One Piece. Muarim from a very young age was always a slave to humans, and thus, is very quiet, and has quite a few emotional scars. But despite this, he has still come to believe that human's can be good people, and is even a fatherly figure to one named Tormod.
