OK, I can actually provide more information than some of these threads. However, I can not provide enough to make it super easy.
This was a Dungeons and Dragons paperback novel. I believe it said “Advanced” Dungeons and Dragons on the cover. There were tons of these novels. Paperback. I think they were all paperback, actually. I had no idea there were a lot these when I read this one.
In the one I’m talking about, there is a scene where the main character meets a guide who tells him he must take a fork in the road ahead. As the main dude goes one way(can’t remember if was left or right), he can hear the guide behind him say, “I would have gone the other way…”, but he keeps going.
There is a secondary main character who is not human. I can’t remember what kind of creature he was, but he turns into a dragon at the end and accompanies the main character. I think this guy’s name started with “M”, but not sure.
I read it between 1988-1992, I’d say. Can not confirm the publishing date. It may have been older or fresh. I think all those books were straight to paperback.
It was kind of thick. A few hundred pages for sure. Standard length for these books, I believe.
Anyway, does this provide enough information for anyone to identify it? Thanks.
