Heh yeah, and the fanfic versions are often so much fun! xD I mentioned medieval Middle Eastern writings about Korea (Silla at the time) in a blog post: "Silla was known in the Middle East, with scholars such as Ibn Khurdaziba in the ninth century writing about Silla as a land beyond China where Muslims happily settled because it was a such a good and plentiful land . . . In the Persian epic poem Kush-Nama the hero Abtin marries Fararang, a princess of Basila which is alleged to be a mythical version of Silla." https://ljwrites.blog/posts/cheoyong-story/#the-middle-eastern-hypothesis-of-cheoyong-s-origin
