In the Underworld, a massive Earth Water Lizard swam in the waters of the subterranean lake southwest of the Deep Rift Cave...
On its back sat more than ten members of various underground races, primarily comprised of dark dwarves and underground gnomes.
If you looked closely, you would find that although these underground races were dressed differently, they all wore the same sickle-shaped emblem on their chests.
It was the emblem symbolizing the Death God, often used in formal occasions.
In the Underworld, this emblem had another meaning too, signifying that the wearer belonged to a major city-state organization in the western region of the Underworld—the Silent City State Alliance, consisting of many residents from the underground city who believed in the Death God.
