Harry Potter and the Chains that Bind

6th year. Time magic. New teachers. Causality. Year 6 replacement. I continue JKR's characterization, and that means Harry is not a god, no one cuts themselves, there is no implied harem, there is no Mary Sue, Dumbledore/the Weasleys aren't actually evil. If you've read it, go ahead and write me a summary, if this isn't good enough.
