The Lovecraftian Nightmare

Write a horror story inspired by Lovecraft’s universe, detailing the encounter of a curious archaeologist with different cosmic entities or deities.

In keeping with Lovecraftian themes, this story should invoke feelings of dread and terror caused by the protagonist’s struggles with the unknown, the unknowable, and inevitable doom. How does this encounter alter his/her perception of existence? Does he/she embrace the terror or fall into despair and madness?
