"Where Tolkein had the heroes of the realm respond to a great threat, Robert E. Howard's heroes are self-motivated outsiders come to make their mark and tell their own story.

Christian McCrea conquers the Rastan Saga, and it's homage to Robert E. Howard's Conan stories.

The article mentions the low-fantasy genre invented and largely defined by Robert E. Howard. If you're interested in him, there's no need to venture farther than Wikisource.

It is interesting to note that there is an article about Howard fantasy and Lovecraft fantasy in the same issue; Howard and Lovecraft were correspondents and, apparently, friends.
