I am the GM. I am GOD. I have no character. I am every character. I am the wind in your hair. The sun on your back, the chill in your spine. 

Actually I've got a couple or three in mind to throw in with the groups for funzies. 
One of them is a massage therapist and holistic healer type I might put with the boat. 
I may put some sort of criminal or extreme sports athelete with the asylum

Another one or two are floating in my head.
