Hades

William kept his crystal green eyes on his office... but it wasn't an empty chair, someone sat on it

"Haa..." a dark gloomy voice echoed, and the tapping of long nails on the surface of the table followed. "A Demigod hails me..."

William kept his stern eyes on the unearthly being in his seat, relaxed like he owned it and everything in the world.

Hades was before William, the very god of the underworld no one has ever meddled with. William was unable to see the face of this being for he had a beast skull for a mask, But the mask only covered his eyes and nose, his lips were to the view that pressed in a wide line of smirk.

Hades' hand flipped the pages of a book he held like he was reading it, while the other hand tapped on the surface of the table echoing in the quietness.

"Hades," William said.

Hades made no effort in speaking to William, simply keeping attention on the book.
