If I recall correctly, the Slomon K'Hara script is based off Daam K'Vosh script, but not the same as it. Language systems evolve, even when "normal" communication is symbolic and perfect. Some concepts are difficult to express symbolicly, and that's where the script comes in. Not to mention it looks flippin' sweet.
And there's actually a particular passage that I thought was a bit too easy to decipher, keep looking for key phrases and you might figure it out. If you do, please don't just tell everyone though... you can brag all you want though!:D
