In earlier drafts of the History of elves, Tû is a mysterious character, described as " the greatest wizard/magician in the world", living in deep caves, becoming some sort of mentor/ruler for the Avari elves before the awakening of Men, and who tried to likewise tutor the Men before he opposed them when they became hostile toward the elves.
Later the name seems to have been recycled by Tolkien for another figure that would evolve into the Silmarillion's Sauron, but was later abandonned.
Has someone ever imagined a Far East campaign in ME with Tû as the main villain/antagonist?
I like Gilfanon’s Tale and I like Tû. I don’t know why various websites connect him with Thû (Sauron), as the latter evolved from Tevildo Prince of Cats. Tû is good, or neutral at worst, sort of a Radagast type. He is a fay (Maia), like all wizards in the stories, but there the similarity to Thû ends. Furthermore, in Gilfanon’s Tale there is another character, Fankil, who IS an evil fay described as Melko’s Lieutenant and who is a more Thû-like character than Tû.
Gilfanon’s Tale is a very imaginative story, and never rejected outright, as we see some of the ideas reemerge in The Awakening of the Quendi (XI) and Athrabeth Finrod ah Andreth (X)—if not the specifics, at least the mood and the essence. I love that Tolkien invents a wizard character wherever he needs one, and never felt bound to the idea of there being only five.
