An excellent age, very well crafted and rendered but I can see some minor problems.
Colour coded puzzles are fine but what about the thousands of people that are colour blind. For them your first two puzzles are impossible. Ok let us assume that they are not colour blind, and that they have solved the first puzzle and have found the lever to open the door. They are confronted with another lever and another colour puzzle with no idea nor no clue as to what the solution could be (except for an untranslatable ? Dni ? phrase). It may be a good idea to give the KI the ability to read and translate the Dni script. IE if we see a Dni script, it is clickable and by doing so brings up the in-game translation of what the words or phrase are suppose to mean.
It is possible to cheat to get around this puzzle. By just standing in front of the puzzle you can /jump 160, walk over a few paces and /jump -20 and WAH-LAH we are standing in front of the first tree station where all we have to do is register the KI.
BUT there is a problem when you use this cheat, when you go to climb the final Ladder you will be linked back to your Relto. To get around this you must solve all puzzles. At least that is what I beleave...
EDIT On the UAM Shard while in Adrael the /jump command has been disabled to prevent this cheat....
Suggestion You might want to disable the /spawn command also
