a greek god, the god of darkness
The primordial God Erebus (Έρεβος) meaning darkness. Son of Chaos.
Erebus (pron.: /ˈɛrəbəs/), alsoErebos (Greek: Ἔρεβος, "deep darkness, shadow")
Erebos is the Ancient Greek God of Shadow and Darkness, it is often thought that he is the son of Hades (In Roman Mythology he is known as Pluto) , the Greek God of the Underworld - People often call the Underworld, Hades. But Erebos is actually the son of Chaos, darkness itself but no intercourse was used to produce him. Much like Athena (Daughter of Zeus, Goddess of Battle Strategies). Erebos married his sister, Nyx, the goddess of the Night.
Erebus does not have a surviving artistic rendering from ancient Greece. He was only the personification of darkness.
Hades, the Greek god of the underworld, is the owner of the Helm of Darkness. It is one of his most powerful possessions, allowing him to become invisible or manipulate darkness at will.
The Greek word for shadow is skia. This word comes from the other Greek word "skotos" which also means "darkness." The symbols of the word are described as O with a line coming from the top of it, then there is a K, an I, then an a with a accent mark over it.
