Ba

A ba (plural, bau) is the part of ones soul that represents an individual's personality and continues to live on after one's body has died. One's ba often travels in the Duat while sleeping, often resulting in visions, particularly in the case of magicians. A ba may also travel through time and space, such as when Sadie Kane witnessed Osiris's fateful birthday part several thousand years ago. A ba may occasionally act as a guardian.

A ba often takes on the shape of some sort of bird with a human head. The type of bird may vary by individual, representing one's personality.
