A lost tale of Jeff?

Thanks to the wonderful skills taught to me over the last few years I have deciphered this ancient rune. My research leads me to believe it's a reference to the lost tale: 'The single combat of Jeff the Transgendered Platypus and his foster brother/sister Terry the Hermaphrodite Peacock!' Naturally I will continue my research into this matter in the hope that some day we may all understand why Jeff would commit such a appalling kin-slaying!
