There are certain words that are just used too often in fantasy book titles. (The same goes for other genres, but that is another post.)
I have constructed the following list of banned words in the titles of books. Not that I won't read books with these words in their titles, necessarily, or that there are no good books that use these words, it's just that I am sick of seeing books called "The Dragon Wizard Tales" or "Legend of the Elf Knight". The words are just overused, and they immediately put me off.
The banned words are, in no particular order:
wizard ring lord elf time dragon winter crown king magic magician wand sword fire spell demon dune tale legend wyrm fate knight ship bard god gods tower
