You know it occurs to me after reading Duma Key that Stephen King has accumulated quite the little pantheon of his own Elder Gods. Things that wait, sleeping in the outer dark and the lost places of the world. Not Cthulhu or Yog Sothoth or Nyarlathotep, but Tak and Perse, and IT and whatever the Library Policeman was. I think H.P. Lovecraft would have approved.
