Kemetic/Egyptian in origin, Bennu is the name of a particular and special ancient Kemetic bird.  This majestic bird flew over the land for 500 years spreading culture, arts and sciences for all to gather.  After 500 years, the Bennu made a nest from branches and leaves of the earth then fanned its wings over the nest until a fire rose from the pile. 

The bird soared high over this pyre then plunged down into the raging inferno.  After a short time, from the ashes a new majestic Bennu bird emerged.  Flying high above the earth, the Bennu again spread the culture through the arts and sciences over the land for another 500 years.
