The Beard has always existed. It predates, and in fact might have even caused the creation of, the universe.
In times of great peril and need, The Beard seeks out a worthy bearer and enables them with needed gifts of power. The current bearer, RS-Bocephus was blind, deaf, mute and impotent, but alas, worthy of The Beard. He was given the gift of vision, speech, a functioning phallus and partial hearing in one ear.
