Cthulhu, is a difficult God to worship, much less to spell.

It 's important to realise that Cthulhu is not an entity in the sense that other monsters are entities, but rather a fundamental force of the universe. Indeed the fundamental forces of the exoteric universe are:

  • Gravity
  • Electromagnetism
  • Strong Interaction
  • Weak Interaction

The esotericist would be inclined to add:

  • Cthulhu
  • Nyarlathotep
