This article is about Finnish deity. For the DC Comics character, see Dominus (DC Comics).
In Finnish mythology, Tuoni (Finnish pronunciation:[ˈtuo̯ni]) was the god of Tuonela (the world of the dead), and darkness personified. He was the husband of Tuonetar. Their children included Kipu-Tyttö, Tuonenpoika, and Loviatar, who were divinities of suffering. When in human form, he appears as an old man with three fingers on each hand and a hat of darkness.
