Is There Any Sand to the Story?

There's also some that I would consider the we don't know books, like the Rehong C Codex donated to the Hungarian Academy of Sciences in the early 19th century. Some people believe it is a hoax, but so far at the time of the recording, no one has proven that to be the case. It just showed up with an alphabet all its own. Not only do we not know what it's about because it's written in like the Soya and uncracked code. We also don't know where it comes from.
