Tower of Uuxaem

This is one I did quite some time ago but have always really liked - or at least liked the idea of. I've got plans for an rpg adventure involving this tower that has been warped by chaos. This is sort of a high level creature that will appear in a series that I've nominally titled "Shadows of the Umbra Palace". I've got a bit of other work to do before I revisit this, but the desire is there. Happy gaming!
