The story of heaven and how it was corrupted is a long and disgraceful story. It all began with the creation of the four archangels. When God had finished creating Heaven, he needed someone to protect and nurture it. So he bent down, and picked up a piece of stone. He then formed it into a being with large, glorious wings, stretching far out. "You shall be named Michael, the first archangel, and the protector of Heaven. You shall be the general of Heaven's forces, and second only to me in command." "Thank you Father, I will do my duties with proudness."
God then took a piece of his own grace, and formed a second being with wings. But this being exceeded anything God had ever created. Its wings were enormous, with an incredible colour and beautiful, long feathers. It's stood there, almost a head taller than both Michael and God, with an unbelievably beautiful face. His eyes shone blue with a bright golden ring surrounding the pupil. His hair was long and dark brown, and his body was massive, with enormous muscles and tall shoulders. Michael gasped at the sight of his beautiful brother, and how majestic his appearance was. "You shall be named Lucifer, the second archangel, and shall be Heaven's second in command, only exceeded by your brother Michael and then me. You represent the beauty and cleverness of creation, and shall be the bond which holds the Heavens together. You shall be my first assistant in creation, helping me design the cosmos. Understood?" "Yes father." Lucifer answered with a voice which boomed of authority, but still sounding gentle. "Great! Now, my children, I have a task for you."
"Long before I created Heaven, I created a being which I called Leviathan. I gave them a home, and I foolishly gave them immortality. Both of you have immortality, but not on this scale. Killing them would take colossal amounts of energy, which would take all of your grace combined, only to kill one. I quickly realized just how monstrous they were, and they destroyed large portions of the world I had created. I want you to throw them far, far away. I can't undo them without undoing large portions of the universe, so I have instead created a prison for them. Far away from here, in the deepest darkness of creation, you will find a door. Beyond this door lies Purgatory, a world of monsters. All monsters of this world shall go there after death, and it shall be the final resting place for the leviathan. Go now, seek out these monsters, and do with them as I've said."
