Cyric Prince of Lies and the Dark Sun
Cyric (seer-ick) is a Greater deity and holds the portfolios of Murder, Lies, Intrigue, Deception and Illusion. He is a petty, self-centered, megalomaniacal deity who holds himself above all others. He has an immense following throughout Faerun. The unholy radiance of the Dark Sun draws power-hungry mortals like moths to a flame and then inexorably consumes them. He has assumed many guises since his ascension: a bloody wraith, a cloud of poisonous smoke, or a sudden gloom containing the phantom images of whirling human skulls and the intent gaze of two black eyes. However his true form is believed to be that of a slim man with blazing dark eyes and chalk-white skin.
Once mortal, Cyric was elevated to divine status by Ao at the conclusion of the Time of Troubles in 1358 DR. Upon his ascension, Cyric claimed the portfolios of Bane, Myrkul and Bhaal, largely subsuming their churches into his faith as well. The Dark Sun then slew Leira, Lady of the Mists, absorbing her portfolios Deception, Illusion, Mist and Shadow.
A decade later a Cyric plotted to again increase his power he inadvertently lost his mind. This temporary weakness allowed Kelemvor to steal the portfolio of ‘death’ from him. Once regaining his senses he was able to steal some of the powers of the god Mask, the Master of All Thieves. These powers included the portfolio of intrigue.
