Ensure the Decemvirate doesn't take advantage of Pathfinder agents.
As of August 15, 2013, the Shadow Lodge faction is no longer a playable faction in Pathfinder Society Organized Play.
For decades, a growing segment of the Pathfinder Society's membership has become disillusioned with the Decemvirate. Whether they hold personal grudges against the masked leaders of the Society for slights they feel were never remedied or watched too many of their friends suffer for the good of a Society that seemed to thank them very little, these rebels' numbers have surged in recent years, swelling the Shadow Lodge's membership. In 4710 ar, several fringe cells of the underground resistance movement broke off from the main body of the Shadow Lodge, and began a series of open attacks on the Grand Lodge and those loyal to it. The Decemvirate, recognizing that there was a real problem to be addressed, quelled the rebellion by bringing the Shadow Lodge back into the fold, acquiescing to some of their demands, and sending strike forces to hunt down and eliminate remaining cells of radical Shadow Lodge agents. Many remaining Shadow Lodge agents still feel the Decemvirate has further to go to remedy the injustices carried out in the Society's name, though they are glad to be in good standing with the Society once again—even if many also believe they were brought back into the Grand Lodge so the Ten could keep a closer eye on them.
A former Pathfinder field agent whose name has been lost in the dust of the tomb in which he was left for dead, Grandmaster Torch has spent decades building an empire of spies, informants, and double agents within the Pathfinder Society and without. From his sewer lair in the Puddles (located in a generally dry section known as the Siphons), Torch used his position as a notorious information broker to rack up a sizable debt of favors owed him by the Pathfinder Society. When his role as the mastermind behind the Shadow Lodge was revealed, the Decemvirate was quick to pay off these outstanding favors, meeting some of Torch's demands and hopefully precluding all-out mutiny among the Pathfinder ranks. Despite being on relatively good terms with the Ten at the moment, Torch is still suspicious of how much they've actually bent in the face of adversity. Ever suffering from a terrible curse that left him covered head to toe in vicious burn scars, Grandmaster Torch may yet require more than honeyed words and hollow promises to truly smooth things over.
The Shadow Lodge Pathfinder
Most Pathfinders claiming membership in the Shadow Lodge have a personal grudge against the Decemvirate. Whether they themselves were victims of the Ten's apathy regarding their well-being or saw friends or relatives suffer because of the Society's inaction, tragedy and resentment push most Shadow Lodge members into the organization's ranks. But while Shadow Lodge Pathfinders may not like the Decemvirate very much, they nevertheless want the Society to prosper, and do what they must to assist their fellow agents, especially when the Ten send them into harm's way. Most Shadow Lodge Pathfinders are chaotic-aligned.
