Season 2 of the Pathfinder Society Roleplaying Guild campaign ran from August 2010 to July 2011. The season is referred to as the Year of the Shadow Lodge due to the prominent appearances of a rogue group of Pathfinders called the Shadow Lodge and the Pathfinder Society's attempts in bringing them back into the fold over the course of the season's plot. At the start of this season, no new factions were introduced.
During the annual celebration of the city's first military victory and its freedom, the Passion of the First Siege of Absalom, a rogue Pathfinder agent, Charvion Eater-of-Bones, attempts an attack on Absalom with a thought non-existent group of Pathfinders named the the Shadow Lodge. During this attack, Charvion attempts to steal a newly discovered artifact, the Cage of Spirit Echoes, but Pathfinders step in and prevent his theft from coming to fruition. After their defeat in a full assault on Absalom, the rogue Shadow Lodge attempts to assassinate Venture-Captain Drandle Dreng by impersonating him and leading Pathfinders on a wild-goose chase. The Pathfinders realize this ruse and kill the assassin before he is able to cause complete his mission on Drandle Dreng. Knowing they will need more allies in order to compete against the size of the Pathfinder Society, the rogue Shadow Lodge heads to the Lands of the Linnorm Kings and Irrisen in hopes to convince enemies of the society to join their plight. A Shadow Lodge agent in Whitethrone, Caggrigar, receives word from an inside agent in the Grand Lodge that a powerful prophecy lies in ancient ruins of The Worldwound. Hopeful that this is the edge they need against the Pathfinder Society, Caggrigar and a elite group of Shadow Lodge agents head into the Worldwound in search for The Sarkorian Prophecy. Knowing the Pathfinder Society can not let the Shadow Lodge find this relic first, the sends a group of Pathfinders out to locate this as well. During their travels in the Worldwound, the Pathfinders, after attempting to bring them back into the Pathfinder Society, eliminate the rogue Shadow Lodge agents. The Pathfinders kill Caggrigar who had, just moments before, found the Sarkorian Prophecy before it was used against them.
When the Society arrives to offer assistance to a society contact in Whitethrone, Rognvald Skagni, the society realizes that the Shadow Lodge has gotten to him to try and use him as a bargaining chip for critical political information. The Shadow Lodge, able to act on some of Rognvald's research notes, head deep into the frozen north in search for an ancient artifact to use against the society. The Pathfinder society pursues the Shadow Lodge into the city where the Shadow Lodge has convinced the town to ban any presence of the Pathfinder Society. After careful negotiations, the Pathfinders are allowed inside the town and find the Shadow Lodge's hidden base under a brewery. Inside, they locate documentation regarding the Shadow Lodge's current trek in the north to a location called Keep of the Huscarl King, that houses an ancient weapon, Jedrek's Shard. Hot on the Shadow Lodge's trail, but still having quite a distance between them, the Pathfinder Society meets a local barbarian tribe that, after telling them of their worthiness, provide the Pathfinders a shortcut to the keep that allows them to arrive just as the Shadow Lodge does. After an intense battle with the Shadow Lodge, the Pathfinders prevail and are given a choice about the outcome of Jedrek's Shard. Shadow Lodge member and heir to one of Taldor's most wealthiest families, Chalfon Dalsine, catches Oppara Venture-Captain Muesello using illegal Sarenite cultists to smuggle artifacts out of Taldor and attempts to get the Society banned from Taldor because of it. The Decemvirate sends a group of Pathfinder agents to help Muesello out of this situation and attempt to reason with the officals of Taldor. Chalfon catches wind of the Pathfinder's actions and then, in a fury, kills the sister of Qadira faction leader, Muhlia al'Jakri. This leads to Muhlia al'Jakri killing Jacquo Dalsine, which forces her to retire.
The Pathfinders are sent to Sothis on a urgent missive from Venture-Captain Norden Balentiir that many Pathfinders have gone missing as well as the vaults holding relics and artifacts has been robbed. After retracing the steps of the thieves, the Pathfinders are able to track down all of the missing artifacts and locate the leader of the Shadow Lodge in Sothis, Hondo Heru. He tells the Pathfinders that he was told by someone named "The Spider" to steal the relics and kill the Pathfinders.
On word that the Cathedral of Aroden, part church and part Pathfinder Society Lodge, has recently been invaded by Hobgoblins, the Decemvirate dispatches a team of Pathfinders to break into the cathedral and rescue any survivors, one being Venture-Captain Brackett. As the Pathfinders progress through the cathedral, they kill the commander of the invading hobgoblins, Hagla, and save all of the hostages. After resucing him, Venture-Captain Brackett explains that the real mastermind behind this ruse was not Hagla, but a person by the name of "The Spider". As well, the Sapphire Sage, Amenopheus, has pretended to defect to the Shadow Lodge in order to uncover their secrets, but has been captured. "The Spider", having gained notoriety in the city of Almas, attempts to tarnish the Pathfinder Society's name by using Amenopheus' ruse as proof that the Pathfinder Society is spying on the city of Almas. The Pathfinder Society must collect evidence of The Spider's corruption and use it as counter-arguments in the speech. Successfully convincing the city of Almas of The Spider's actions, she is captured, but quickly escapes and confronts the Pathfinders directly. After defeating The Spider, revealed to be Dorianna Ouidda, the Pathfinders find a note stating an assassination is about to take place.  The Pathfinders found out that this assassination is targeted for Grandmaster Torch and are requested to help Torch anyway he requests. Grandmaster Torch tells the Pathfinders of a Red Mantis cell that is hiding inside the Allegro College in Absalom and requests they eliminate that threat. As the Pathfinders eliminate the college of any Red Mantis, they encounter the assassin that was chosen to kill Grandmaster Torch. The Pathfinders overtake the assassin and stop the assassination attempt on Grandmaster Torch. Grateful of their help, the Pathfinders are provided history and information about Grandmaster Torch, how he was the leader of the rogue Shadow Lodge group, and how because of the Pathfinder's help, the rogue Shadow Lodge is no more. Torch declares a truce with the Decemvirate... for now.
