I get asked this question all the time.  Usually at cons someone sees my Cthulhu Idols and ask some variant of “What is Cthulhu?”  I sort of assume that everyone knows about Cthulhu and it shocked me that they don’t.  Also to be honest I am terrible at explaining it.

So since my “Elevator Pitch” is so bad I created a small primer to help people answer “What is Cthulhu?”  Hopefully it will aid you explaining the unexplainable to your friends and family.
