At the Mountains of Madness

A scientific expedition in Antarctica discovers a massive, non-Euclidean city hidden behind a mountain range, preserved by the ice. As they explore the labyrinthine ruins, the geologists decipher murals that tell the history of an alien race that enslaved shapeless beasts to build their civilization. The horror stems from the realization that these slaves—the Shoggoths—are still alive and waiting in the darkness. It is a harrowing tale of scientific hubris and the terror of deep time.
