Ooooh. I see...
There's 'Nigritude' which is also a synonym for night or darkness.
Ummm... 'Apep' which is the personification of evil, or the serpent of the Nile in egyptian terms.
'Fafnir' which was a norse story of a dwarf who was turned into a dragon. It's more or less the name which means 'greed.'
Also 'Ladon,' who according to Greek Mythology, was a hundred headed dragon that guarded the garden of Hesperides.
And lastly, there's 'Darksol,' which is an enemy off an old sega game, but also doubles in meaning 'Dark soul.'
But, I believe I am going to use 'Nigritude' for a dragon of mine... ^_^V
