personally, I think one three and four should be combined in some way. like the evil guy convinces the good guy to do somethin bad, then vanishes, and then goog guy is banished, and along the way, several clues to an ancient battle or whatever comes out, and it's like 'Woah, we did this before.' and then towards the end the evil dude reveals what he's tryin to do is break out of a cycle. or somethin like that. like some basic fusion of 1, 3, and 4. sounds like a nice story, at the basics.
