After defeating the Titans, the gods divided the world among themselves; Zeus took the skies, Poseidon the seas, and Hades, deceived by Zeus, was left with the Underworld. The gods created the mortals, whose worship maintained the god's immortality. Over time, however, the mortals began to blaspheme and defy their creators. The demigod Perseus was born to the mortal queen Danae who was conceived by Zeus during the siege of King Acrisius at Mount Olympus. Upon discovering her conception, an enraged Acrisius orders the queen's execution and locks the child in a chest with her corpse. In Zeus' retaliation, a lightning bolt strikes the king and severely deforms him. The king then throws the chest into the sea. Thereafter, Perseus is found and raised by the fisherman Spyros and his wife Marmara.
