In Varisia's bustling frontier town of Magnimar, the Pathfinder Society's newest lodge recruits a team of rookie Pathfinder agents to track down rogue agent Natayla Vancaskerkin - who also happens to be a member of the Varisian criminals known as the Sczarni. Yet, when Magnimar's newest heroes track down the missing woman, they find far more than a Pathfinder on the run, becoming embroiled in a quickly expanding hunt for a fragmented artifact from the height of the ancient empire of Thassilon that will take them to some of the most dangerous corners of Varisia! Shards of Sin is a Pathfinder Roleplaying Game adventure for 1st-level characters. This volume begins the Shattered Star Adventure Path, outlining the fabulous powers of the Sihedron artifact and its seven fragments that form the basis of an epic new campaign. New monsters from the wilds of Varisia fill the Pathfinder Bestiary, while Bill Ward (Return of the Sword) begins a new novella in the Pathfinder's Journal.
