Cyric is a deity in the fictional Forgotten Realms campaign setting, a branch of the Dungeons & Dragons fantasy role-playing game. Cyric is known by many titles, including: the Prince of Lies, the Dark Sun, the Black Sun, the Mad God, and the Lord of Three Crowns. Cyric is closely associated with the essence of murder, strife, lies, and intrigue.
Cyric is not subservient to any other deity in the Faerûnian Pantheon. He has made himself enemies with Mystra (Second Incarnation), Kelemvor, Oghma, Azuth, Mask, Tyr, Torm, and Iyachtu Xvim (now Bane). The faith of Cyric is symbolized on the Forgotten Realms continent of Faerûn by his symbol: a white jawless skull on black or purple sunburst. His alignment in the game's mechanics is Chaotic Evil. He was a Greater Power, and he ruled supreme in his divine realm, the Supreme Throne.
