My idea is that a new Valar, the Valar of Time. Aëon. Who seeks to fix what Melkor did to the original song. However in the process, messed up the music which caused an even greater discord. Merging all the time periods into one. Making new characters and making new enemies. Ex: an Orc can be a hero. Or half dwarf, half elven characters can exist. Or have a world where Turin fought with the fellowship instead of Aragorn. I have the idea. If anyone is interested.
