Eventually, one of the Aeons, Sophia “of the Epinoia”, disrupts the harmony of these processes by engaging in creative activity without the participation or consent of the Spirit of the Monad and without the aid of a male consort. The creative power of her thought produces an entity named Yaltabaoth, who is the first of a series of incomplete, demonic entities called the Archons. Yaltabaoth, whose character is malevolent and arrogant, also has a grotesque form. His head is that of a lion while he possesses a serpentine body. Recognizing the deformed, imperfect nature of her offspring, Sophia attempts to conceal it somewhere where the other Aeons will not discover it. The act of hiding Yaltabaoth also has the result that Yaltabaoth himself remains ignorant of the upper world and the other Aeons.
