What is the author's style in The Eyes of the Dragon by Stephen King?

Despite being a novel set in a medieval type setting, the language in this novel is simple English, the type one would expect in a modern novel. Stephen King does not attempt to write his dialogue in Old English, nor does he attempt to sanctify the story with large words and formal speech. However, Stephen King does use unfamiliar words throughout the novel, such as goshawk in order to describe the rank of an officer in the royal guard. These words add to the foreign feel of the novel, suggesting to the reader, as the authorial voice also suggests, that the setting is not in the past but that Delain exists in a world altogether different from earth.
