@Skathix Very quick summary: Cthulhu is a creature from the stories of H.P. Lovecraft. His stories focus on
Cosmic Horror. The primary theme of Cosmic Horror is that humans are insignificant and inconsequential in the greater cosmic reality and worth no notice whatsoever, that there are creatures so great that they are utterly indifference to the existence of humanity, much like we are utterly indifferent to the existence of ants.
