Who wrote the first Cthulhu Mythos story?

The first story in the Cthulhu Mythos is 'The Call of Cthulhu' by H. P. Lovecraft. It set the tone and introduced many key elements of the mythos.

The significance of the first Cthulhu Mythos story lies in its ability to create a sense of dread and unease. It was the origin of the idea of ancient, powerful, and malevolent beings that exist outside our normal perception. It's a story that has since been built upon by countless others, but it started the whole concept, which is really cool.

August Derleth also made significant contributions. He continued to develop the Mythos after Lovecraft's death. His works added new elements and stories that are considered important for those new to the Cthulhu Mythos.

Another great one could be 'At the Mountains of Madness'. It takes the reader on an Antarctic adventure where the characters uncover ancient and dreadful secrets related to the Cthulhu Mythos. It's full of Lovecraft's signature atmosphere of dread and the idea that there are things in the universe that man was not meant to know. It also gives a lot of background about the Elder Things which are important in the Mythos.

One of the best is 'The Call of Cthulhu' by H.P. Lovecraft. It introduced the iconic Cthulhu and the vast, mind - bending Mythos. It weaves a tale of horror and the discovery of an ancient, malevolent entity lurking beneath the surface of our world, with a great sense of atmosphere and dread.

One of the best first Cthulhu Mythos stories is 'The Call of Cthulhu' by H.P. Lovecraft. It's a classic that really introduces the essence of the Mythos. It has this great build - up of mystery and horror, leading the reader into a world of ancient, malevolent beings and cults.

One popular author is Thomas Ligotti. His works often blend the elements of Cthulhu Mythos with his unique brand of existential horror. He has a way of making the reader question their own sanity and the nature of reality, much like the classic Cthulhu Mythos tales.

Cthulhu himself is a very popular character. He is this huge, tentacle - faced monstrosity that represents the cosmic horror. Another one is Nyarlathotep, often depicted as a shape - shifter. And there's also Hastur, the King in Yellow.

There might be cultists as well. These are the followers of the Cthulhu - related entities. They are usually depicted as being fanatical in their beliefs and willing to do whatever it takes to serve their dark masters. They can be quite menacing as they try to carry out their rituals or stop the investigators from interfering.
