* Akallabeth witch hunts -- what happened to the Faithful during the corruption of Ar-Pharazon?
* Morgoth/Sauron (why is this pairing never done?)
* Elladan/Gil-Galad -- a result of the Library of Moria random pairing generator. Very AU, but hey, it could have happened.
* Thranduil/Celeborn -- not very many with this pairing
* "Never Ever"
