Below I have five concepts and super ugly pen sketches.  We will have a quick poll over the next day and then I will get to work on it!

This idea would be three different colors of Spirit Kitty around some sort of stone bowl.  I imagine them to be something like the three fates. 

This is a pretty easy concept, a spirit kitty sleeping on top of a tombstone. 

I have previously designed a series of D20 pins that all feature a big D20 as well as a triangle frame element.  This would be an addition to that series.
