Hades, was the ancient Greek god of the underworld. Hades, god of the dead, was a fearsome figure to those still living; in no hurry to meet him, they were reluctant to swear oaths in his name, and averted their faces when sacrificing to him.
Since precious minerals come from under the earth (i.e., the “underworld” ruled by Hades), he was considered to have control of these as well, and was referred to as Plouton, related to the word for “wealth”, hence the Roman name Pluto.
CHARGE OF THE DARK GOD
Hades
I am the shadow in the bright day, I am the reminder of mortality at the height of living. I am the never-ending veil of Night where the Star Goddess dances. I am the Death that must be so that Life may 
continue, for behold, Life is immortal because the living must die.
I am the strength that protects, that limits. I am the power that says No, No Further, and That Is Enough. I am the things that may not be spoken of, and I am the laughter at the edge of Death.
Come with me into the warm enfolding dark, feel my caresses in the hands, in the mouth, in the body of one you love, and be transformed.
Gather in the moonless night and speak in unknown tongues. The Dark Mother and I will listen. Sing to us and cry out and the Power will be yours to unfold.
Blow me a kiss when the sky is dark, and I will smile, but no kiss returns, for my kiss is the final one for all mortal flesh.
