Professor Tolkien has created one of the most complex and rich fictional mythologies found in twentieth century fiction. There is both detail and ambiguity to be found in his collected works. For example, the line of Númenórean Kings or the family tree of Elrond are clearly explored and catalogued. Yet there are many more obscure and esoteric references littering the various texts, that pique the imagination by alluding to more nebulous people and events. What was the fate of the two Blue Wizards, Alatar and Pallando? What was so special about Queen Berúthiel cats which she used as spies? Are there really Were-worms "the East of East"? It is this balance between richly detailed faux heraldry and vague apocrypha which makes Middle-earth such a credible and living world.
