Allright, I suppose the results I have are enough to go on. based on those results, and my own personal preferences, I'm going to do write proposals for the following:
"Not what they seem", undead, arctic, desert, and "magic disasters". I know that some other choices were more popular than some that I chose to work on; these are up for grabs from anyone else that wants to work on them.
Some of the critters from the more popular selections could fit into the ones you've picked. For instance, the magic golem is a perfect fit for a magical disaster.
