I have long suspected and predicted that the final dungeon will incorporate all of the Scribblers' beliefs somehow, but I really like this explanation for why it would do so.
So far we've seen a rogue's deception, Kraagor's might, and the invisible creatures could be like Lirian's guardians. Maybe the trap magic is meant to resemble Durokan's belief in magic, leaving only Soon's honor left to come into play.
Also, I guess V leveled up against the Nightcrawler in Firmament, because with the +1 from the ioun stone, that would require Level 17 from the calcuations I'm seeing, and the forcecage in the tunnel was "34 hours" which would have been level 16 -- twice (level +1) from the ioun stone at the time.
