Artemis Entreri (once known as Barrabus the Gray) was a ruthless assassin and the former arch-nemesis of Drizzt Do'Urden. A cunning and tactical assassin, Entreri lived an empty life, devoid of any kind of pleasure, existing only to kill. The passage of time caused him to soften his sentiments, but never his fighting edge. He was credited with being one of the most feared and effective assassins in Faerûn.
