Heimdallr

A spirit born from a collection of light. The pink core in its center is said to be full of strong light magic. Seeing as they do not go after animals or humans without magic power, it is thought that they are attracted to the magic power that certain humans have. Though they move slowly, since they can reflect light using the swirling portion around them to hide themselves, they are said to be able to sneak up on just about anyone.
