Cthulhu Dark Ages
Greek warrior-monk who carried a strange artifact
Brother Agathon was a pious warrior-monk in the service of Senior Brother Gudman. A tireless scout, teacher, and sentry, Brother Agathon acted as the forward liaison for the troupe with villages and towns ahead.
Brother Agathon befriended Senior Brother Gudman in the Byzantine campaign, and had been by his side ever since, until his untimely and mysterious demise in the devil-taken town of Asparn.
In his saddlebag was found a black stone of unknown origin, the Calx Oscura.
