The Ebon Triad is an evil cult of heretics from the churches of three evil Greyhawk deities – Erythnul, Hextor, and Vecna. They believe that their deities represent a fragmented divinity, and that through their actions they can merge the power of their three deities into one overdeity of extreme and unimaginable power. The Ebon Triad has cells throughout Oerth, each working to raise funds to finance their ambitious project.
The official churches of Erythnul, Hextor, and Vecna are displeased with the foundation of the Ebon Triad. Tradition and belief have always kept these three churches at odds with each other, and the majority of these faithful have no wish to see the glory and power of their patron deity “diluted” through mixing with “lesser” religions. The fact that their deities continue to grant spells to the cultists of the Ebon Triad is vexing and disturbing to the traditionalists, especially to the church of Hextor, whose rigid faith cannot square the contradiction. Word of the heresy has not spread far from the three churches, who keep accounts brutally suppressed before the radical ideas of the Ebon Triad gain more converts.
To most people, however, the idea that a mortal cult could bind gods as powerful as Erythnul, Hextor, and Vecna is extremely doubtful, even preposterous.
The symbol of the Ebon Triad is a black triangle with the unholy symbols of Erythnul, Hextor, and Vecna each carved into one of the triangle’s three points.
