Those authors are nothing compared to Howard's Hyboria, because there must be at least fourty books on Conan and his adventures, as well as board games, computer games, a large role playing game from the UK -mongoose publishing, etc.

There is no true fantasy horror series though unfortunately other than Ravenloft, but it isn't fully developed and it would have been better to make it more serious, it's for a lower age group, but going back to the books on Hyborea, they are basically the only choice other than a few smaller fantasy series.

Hold on here. I have a book called "Conan: The Rebel" written by Poul Anderson. It is copyrighted in 1980, making it one of the older books in the series.
