Fatbur Bengtzon is a mutated beaver from the supplement "Vid Regnbågens Slut" (At the End of the Rainbow). He got psychic powers, and therefore he has been imprisoned by some rascist humans in a big mansion. He is very thankful that the players free him, but just want to go back home and continue to work in the factories and hide his powers so that people won't be afraid of him, and maybe even lynch him.
