Legend says Prabeta, The eldest son of Ignalpha, was a loyally lawful neutral deity like his father.  His fierce loyalty and devotion was short lived however, as eventually he requested Omniscience equal to his father.  When Ignalpha refused him, he demanded that be given Omniscience.  Ignalpha laughed and refused a second time.   Prabeta dwelled on this refusal for centuries, until he became tainted by the obsession.  Finally, he stood before his father, an army of followers behind him, and demanded his earned status as a god of gods.  Again, Ignalpha laughed and said, "THAT you are about to earn."  Prabeta attacked Ignalpha with his army, and though he was quickly defeated, hes become known as god of evil gods. His symbol, the Fallen Dark Sword, represents his failure in battle against his father and banishment to the dark planes.
