In my story Lucifer has repented and was forgiven way earlier than in Supernatural. To Lucifer was restored his title as an Archangel and Morning Star, the brightest of all. He regained his Grace, which during its absent got stronger and equal to Michael's, who is the oldest Archangel. Lucifer got a mission in one of the youngest worlds, which was created only a few thousand years ago. It was truly different from Earth and its people were really different from humans.

Iliuvatar is God's way younger brother and his Valar are different kind of angels, created by Iliuvatar. Maia are wizards, who were given bits of Grace from Valar.

When Lucifer appears in this world, there is a battle going on.
