Well, the author himself likes to play board game. He from time to time uploads his new board game at his social media. Also the other user have mentioned the inspiration from the classic era anime/manga in the series. But for the myths, I think the thing being presented here is too farfetched. I always think that the author uses East Asian myths as inspiration for the divine beings. And also sometimes, the author uses European arts here and there in his story.

So I don't convince that the author use middle east myth for this.
