The Silence of the Stones, an Adventure in D&D 3.5
In a lightless lake, untold fathoms below the surface of the earth, there is a sandy shore, and a road of broken stone that leads to the tower. Not a ripple breaks the glassy surface of the water, but still the tower looks worn and broken, its back broken by some ancient tragedy, consigned to a stilly, desolate abyss.
Then, in the eternal subterranian night, there is a glimmer of light: A sick glowworm of illumination from a ruined tower window that nonetheless stands out like a star. A click, and then- music. A tinny, warped tune: a musicbox dirge that whispers loss to the lifeless underground sea.
