I have a theory....
Okay, a few theories, but bear with me. I've been re-reading the story and the Lost Desert TCG cards that seem to apply to it while waiting for clues.
I think the tablet is not the end of the puzzle, in fact, it's just the beginning. The tablet will reveal the prophecy when we decode it with the library scrolls. When we speak the prophecy to the statue, it will activate whatever it is that Prince Jazan is counting on to help him get the princess, etc. No doubt he'll take his revenge at being spurned by making Sakhmet vanish, as shown in the card.
People were mentioning that in one place it says the prince was 1000 yrs old, and in another, that Qasala was destroyed only 200 yrs ago. I don't really think that's a contradiction. I noticed that he's Prince Jazan the fourth, which reminded me of the Mayor on Buffy the Vampire Slayer, who was Richard Wilkins the third, and also happened to be the first and second as well...so if he struck some sort of evil deal that extended his life but cursed him and doomed the city at the same time.....
Another thing I noticed was the "Forgotten Promise" card. It doesn't say anywhere as to which King proclaimed it, which first daughter of sakhmet it refered to, or even which prince of Qasala she was promised to. So it's no surprise that the Princess has never heard of the agreement. It was probably made several hundred years before, and never fulfilled.
Lots of interesting things to ponder and speculate on while we're twiddling our thumbs between clues, lol. I certainly hope I'm right about this not being the end to the puzzle(s). I hope it's not the end to our travels thru the tombs either, not after all that mapping, lol. The "Lost Ring" card, and all the cards showing Tomos and Nabile encountering the same traps we have seems to indicate that we will be returning there, as they haven't discovered the tomb yet...
I have way too much time on my hands

Oh, P.S. -- for those of you wondering what the heck cards I'm talking about, you can find most of them here:

As several people have noted, a few have had the images removed recently, but i don't have any links for those items right offhand
I may be a cold-blooded jelly donut, but my timing is impeccable.
