Glancing through the "It is said"s of the Appendices, there's a lot to work with. So we can firmly argue that:
- Elrond never fought Angmar. His/Rivendell's involvement carries not one but
two 'it is said's. He just sat at home drinking Dorwinion wine while the men of Arnor fought and died.
- Aragorn I was
not killed by wolves as it is said; much like Anakin Skywalker, he clearly defected to the enemy and became a leader of the Orc armies in the Misty Mountains. He may have lived long enough to be behind the capture and torture of Celebrian.
- The Witch-King was actually entirely absent from the Fall of Angmar - both his presence in Fornost and his appearance on the battlefield are 'said'.
- Gimli never went to Valinor. There's two mentions of the story, one with 'it is said' and the other 'we have heard tell'. Actually, Legolas just got bored with him and shot him in the back one day. "Does
that only count as one?"
- There were actually sixty thousand Istari - it's only
said there were five. The "five wizards" Gandalf mentions are just a club, like the Inklings.
The others are fairly boring; I'm not sure there's a lot you can do with 'maybe Merry and Pippin
weren't entombed next to Aragorn!!!'.
