The Isis Adventure

So I solved the ISIS and I am now questioning the entire hieroglyphics on the ISIS and on the box. Can someone give me a run down on what that actually means and how it relates? To me the deciphered codes are worth so much more than the box and rings themselves. Please send me a PM as I dont want the explanation to be public. Also, I even looked up the symbols and got the letters related to the symbol and the Gardiners letter/number combo as well.

There is quite a lot of information on the forum about the hieroglyphics on the Isis, but you may need to do a bit of digging!

on the box it is for the game but I don't think that they hep finding the codes...
