I wouldn't worry about it overmuch. I really did not care much for R. Thomas' take on the Giant-Kings, as much as I respect his work. The story was good, but it takes, um, a "de Campian" view of them, instead of what modern scholars (such as Dale Rippke) have had to say about them. I think you are safe to ignore the tale. I just threw it up as a possibility some people may like.
