The Underworld is a shadowy and somber realm located beneath the earth. The entrance to the Underworld is often depicted as a dark, foreboding cavern with a gate guarded by the three-headed dog, Cerberus. As one descends, the landscape transforms into a vast, eerie domain of dark, flowing rivers and misty shadows. The River Styx, a black, churning stream, winds through this realm, its waters reflecting the dim, ghostly light of distant, flickering torches. Souls wander aimlessly in the gloomy terrain, which is dotted with ancient, crumbling ruins and desolate fields. In the distance, the palace of Hades stands, a grim structure made of obsidian stone, emanating a cold and oppressive aura.
