Lords of Creation: Ancients of the Void
These shining birds with silver, white, blue and purple plumage roam the skies of the world, singing timeless and unearthly songs. They are rather large and very intelligent, but still animals. A Phoenix mates for eternity, each pair coming together once every hundred years to mate, and if lucky, bear a single egg.
It is said that the only way to kill a Phoenix is to crush their spirit. A caged Phoenix will always die and their mate left to search the world eternally, crying out for its mate.
