Cyric, Prince of Lies

Alignment: Chaotic Evil
Gender: Male
Sphere: Strife
Dominion: Supreme Throne
Priests: Strifeleaders
Adjective: Cyricist
Domain: Madness, Strife, Trickery

The mad god of strife and lies, Cyric is chaos incarnate. He is reviled by his fellow deities, who have time and again intervened to stop his destructive flights of fancy. When he murdered Mystra in the Year of Blue Fire (1385 DR), the entire plane of Dweomerheart exploded, and the resulting Spellplague ravaged the cosmos. Tyr, Lathander, and Sune united to imprison him in his nightmarish playhouse of a plane, the Supreme Throne, where he remains to this day, alone and increasingly insane.
    Cyricists, inspired by the lunatic clergy who call themselves strifeleaders, spread chaos, destruction, and insanity wherever they go. Few can understand what vile disease of the mind could bring a mortal to serve such a deity in the first place, but where his worship takes hold, only misery follows. His wild rantings are inscribed in The Cyrinishad, a tome of ever-changing text that drives any who read it hopelessly mad.
