The Elder Things are fictional extraterrestrial beings created by writer H.P. Lovecraft. They first appeared in the short story "At the Mountains of Madness," published in 1936. Described as starfish-like creatures with a unique, radial symmetry, they possess tentacles and are known for their advanced intelligence and artistic abilities. In Lovecraft's mythos, the Elder Things are ancient and were among the first life forms on Earth. They built vast cities and engaged in complex scientific endeavors. Their history is intertwined with other cosmic entities, such as Cthulhu and the Great Old Ones, contributing to the rich tapestry of Lovecraftian horror.
