Dark and dreadful

The dynast of the dead

Defended by the demonic dog, Cerberus

Life only decays here.

The descendant of Cronus and Rhea

Divine brother of Zeus and Poseidon

Detained Persephone through deception

Don't even mention the demigod: Hercules

Dwelling beneath the earth

Detached from the world

Assumed to be damaged or dangerous

I am Hades, and this is the final destination.
