“And before all the host rode King Brian Boru on a white steed, his white locks blown about his ancient face and eyes strange and fey, so that the wild kerns gazed on him with superstitious awe.”
-The Grey God Passes
In keeping with his terse sense of the supernatural, fey is an excellent adjective for Howard’s stylistic purposes. His use, in the context of the story cited above, in which the hero king rides to his death in a battle that liberates his people, Howard seems to be using it after the Scottish manner. Also, within the narrative Howard reveled in pointing out that Scottish clansmen came to the aid of the Irish against their Viking enemies.
