“The Mother of Birds had watched Erapodis closely his entire life.  His valor in battle and wisdom in rule enthralled her, and eventually she gave in to her selfish temptation out of lust and arrogance.  She appeared in his chamber, irresistible and transcendent, Erapodis' discerning and rational mind deserting him in the face of such splendor.
The offspring was concealed and left with Erapodis. Â She feared that if the other Gods learned of its existence they might conceive to smite it and Erapodis down in retribution. Â She herself may be banished from the Golden Court or perhaps stripped of her immortality. Â Her attempts at secrecy were foolish if not desperate, and it did not take long for the Allfather, the First and Highest Ruler, to become privy to her scheme. Â Although benevolent, he could not condone this blasphemous action and let it go unpunished.
The daughter had all the divine beauty of her mother and, despite her mortal body, was destined to possess the ability to fly.  The Allfather instead cursed her, stripping her of her powers and causing feathers to grow out of her back, noticeably protruding along her spine.  They served as a constant reminder of her irreverence, ostracizing her from both the mortal and immortal worlds.” -M.D. Walter
