The Transition of Juan Romero by H. P. Lovecraft

In a remote mine, two workers descend into a mysterious chasm that seems to defy natural law. As they enter a realm of shadow and surreal terror, only one returns—forever changed. This eerie story explores ancient forces lurking beneath the surface of the earth. Though brief and fragmentary, it builds a powerful atmosphere of dread and wonder. It’s a glimpse into the unknown, in classic Lovecraft fashion.
