The Bennu bird serves as the Egyptian correspondence to the Phoenix, and is said to be the soul of the Sun-GodAmon-Ra. Some of the titles of the Bennu bird were "He Who Came Into Being by Himself," "Ascending One" and "Lord of Jubilees."
It was associated with the rising of the Nile, resurrection and the sun. Because the Bennu represented creation and renewal, it was connected with the Egyptian calendar. Indeed, the Temple of the Bennu was well known for its time-keeping devices.
Bennu is the first Persona of the Sun Arcana. As it ranks up, all of its stat gains are in the Magic Attack, Agility, and Luck stats. Upon being returned to the Velvet Room at MAX Rank, it will yield a Posumudi Stone.
