Looking at your source, it appears as though I stand corrected. Guess it literally means that they rose 25,000 years ago, and it wasn't referring to the man'ari.
Though I do have to say that you're absolutely wrong in saying that there was no source. It was there, just the non-archived version of what you linked and it did say what you were saying, to a shorter degree, so it wasn't just someone putting it in because they thought it was correct... it WAS correct. The difference being my interpretation of what it meant versus the lore from the book.
