Well, that was JRR Tolkien's intent. It's supposed to be from a forgotten part of history. Both The Hobbit and LotR are supposed to be his translations of old books from the actual time period. Each age ends in a battle with a big bag guy. LotR ends the 3rd age with the defeat of Sauron and the 4th age begins. Each age is gradually shorter than the last. I believe the defeat of Hitler was supposed to be the end of the 6th age, which puts us now living in the 7th age. Tolkien put it together that way.
The bunny in that video is Sir Fidgwit....um...infected with lyncanthropy? NJ plot can run with it from there.
For those who haven't played NJ, Sir Fidgwit is a somewhat hyper rabbit scavvy knight played to the hilt by Brian Bender. You have to come see it, even just to hear the voice he uses.
