One day there were the great monster defenders of Zeus, Aphrodite, Ares, Poseidon, Zeus dragon, unicorn, Ares-lion, Poseidon-snake.
Hades came out of hell and brought medusa. He brought a bifrost and a charamander from the depths of Hades. He had a weapon forged by the Titans. Since they were in hades it was a weapon to merge the gods to one.
Hades had it all planned out. He attacked them, there was blood everywhere, and people turned to stone. Hades thought he might lose. He kept going. The storm Zeus channeled was with the sword of the monster. It slashed the monsters and Bipolaris is created.
