The
FireBird can either be the
Phoenix or the Pagan
Rarog.
The Phoenix is a bird made of flames that burns when it dies and is then reborn from the ashes. It is the icon of the circle of life.
The Rarog is a shapeshifter that can either be a hawk/falcon or a whirlwind, derived of one of the main Pagan gods, Svarog and as such it is the icon of clear bright light and fire.
