In terms of Blake's Orc cycle, Urizen serves as a Satanic force similar to Milton's Satan. After Urizen defeats the serpent/Orc figure in the Garden of Eden story, the Orc figure, in the form of Urizen's son Fuzon, battles against him in a story based on Exodus. Urizen, as a pillar of cloud that hinders the Israelites in their journey home, battles against Fuzon, as a pillar of fire that guides them by night. Eventually, Urizen is able to destroy his rebellious son and impose laws upon the Israelites in the form of the Ten Commandments. This also leads to a death of the Israeli society, and the Israelites under Urizen are imprisoned in a similar manner to how they were under the Egyptians. Symbolically, the Orc cycle describes how Urizen and Orc are part of one unified whole with Urizen representing the destructive and older essence while Orc is the young and creative essence.
