My interpretation of the Balrog, Durin’s Bane from Lord of the Rings. I stuck a bit to the movie’s look, but made him a bit more bat like and more smoke than fire. Think Smaug is next. “You shall not pass!” Print - [link]
Like, a book explaining everything about the worlds I guess, maybe with more descriptions on species or races too. I've heard about The Similarion but wasn't sure if that was just a prequel story or if it actually explained a lot more about everything.
