Crypt of Kazarn

This crypt is an area I am working on for a larger module. Though it is a single area, it is rather large. I would call this beta, as there are still some issues that will need to be worked out. This module is heavy on hack and slash, and has a number of trick and traps. As it is one piece of a larger module, there is no quests currently present. I am offering this to the community, in hopes of constructive feedback. Good or bad, I wish to hear it so that I might improve upon the whole.

A background about the Crypt of Kazarn: Kazarn, a once powerful dictator of the surrounding lands, felt the forces of good bearing down on him. He built a crypt and after hiding it locked himself away in it. Clues were left behind. Adventurers anew, in a time where Kazarn is long forgotten, would find the clues, unlock their meaning, and open the crypt, allowing Kazarn once again to spread his rule. This piece begins assuming the heroes have found the crypt entrance.
