Xa'rael is a name that is virtually unheard of (which is not hard to figure since it wasn't widely used and is very, very old). A more known derivative of Xa'rael is Azrael, meaning angel of death. The meaning of the name Xa'rael is unknown, although some believe it could mean something along the lines of angel of suffering/anguish, patron of death, or bearer of the apocalypse (obviously this isn't something you'd want to be named). The origins of this name is unknown, but it is believe to date between 5000 and 3000b.c.
