War is Hell! Valeros is a veteran adventurer whose life as a mercenary lies far in his past. When conflict erupts, however, more aspects of Valeros's past come crashing into the present day than just his soldiering days. Now, separated from his longtime adventuring companions by a burgeoning war and vast distances, Valeros must rely on new allies to prevent a diabolic dragon's sinister machinations from coming to fruition. In an exciting race against the clock, Valeros must make himself part of the crew of the Wandering Star , under the command of former pirate and current Andoren operative Torius Vin, hoping to reach the site of a nascent Hellmouth―a living portal to Hell―before a dragon can use it and a sliver of a slain god to upset the balance of power in the region.  With the aid of the enigmatic sorcerer and spy Vreva, the naga oracle Celeste, and a young Eagle Knight with her own ties to Valeros's past, the iconic fighter and the crew of Wandering Star must overcome the forces of Hell with the fate of Golarion hanging in the balance. From fan-favorite fantasy author Chris A. Jackson ( Pirate's Honor , Pirate's Promise , Pirate's Prophecy ), Operation Hellmouth promises an unforgettable adventure of infernal plotting and family drama on the high seas, set in the award-winning Age of Lost Omens setting for the Pathfinder Roleplaying Game.  Operation Hellmouth is the perfect entry point to the Hellfire Crisis event within the Pathfinder setting, a multi-year conflict that will pit the world's most powerful nations into all-out war. Professional sailor, SFF fan, career biologist, gamer, and author, Chris A. Jackson has a diverse bibliography of science thrillers, nautical fantasy, epic fantasy, science fiction, horror, post-apocalyptic fantasy, and RPG tie-in stories. His game tie-in work includes the Pathfinder, Iron Kingdoms, Shadowrun, Arkham Horror, and Traveller RPGs. He has over 30 novels in print and has won numerous awards, including the 2020 Scribe Award for best tie-in short story. His most recent works include the War of Souls post-apocalyptic fantasy trilogy from Falstaff Books, and the high fantasy Seeds of Darkness trilogy published under his own imprint, Jaxbooks. He and his wife, Anne, quit their perfectly good careers in 2009 to go sailing “for a few years” which turned into 13 due to their success with Chris’s writing career. They never encountered any real pirates during their travels, but Chris has written three different nautical fantasy series, including his tie-in work for Paizo.
