A group of adventurers found themselves on a train headed to The New Frontier. The train was jumped by a group of bandits, the The Free Company of Brethren, whose mechanical humanoids tore into the train. The robbery was stopped by this group of adventurers, Osiris Deschain, Kazimir the Artist, Thorin Stonefoot, and Telos Kirak. These adventurers bonded through this experience, and eventually found themselves in Ectin Falls, the semi capital of The New Frontier. There, they began taking on small jobs, but quickly found themselves embroiled in a hunt for a murderer. This murderer turned out to be Kilvar Stonefoot, Thorin’s brother, who was demonically possessed. During the hunt for Kilvar, Kazimir was magically sent to a demi plane where some sort of devilish entity made a link to him.
After driving Kilvar out of Ectin Falls, the group attends a party at a local baron’s home. There, The Free Company of Brethren once again make an appearance, but are once again stopped by the group. While at the party Kazimir fulfills a contract to kill the local priest. Some of the party recognize that something is off about a few of the guests, and follow them back to a local hotel, the Laughing Stock Hotel. That night, the inn keeper at their inn is captured and taken out of town. When the party follows, they discover that the inn keeper’s captors are wererats. An assassin shows up hunting Kazimir, and while the party successfully kills the assassin, who is also revealed to be a werebeast known as Brother Cloudwalker working for an organization known as The Family, the inn keeper is killed.
The party returns, and investigates the Laughing Stock Hotel. Discovering that the Hotel is the headquarters for the werebeasts, they accept an invitation and Osiris and Kazimir attend a meeting with the leader of the werebeasts, a Master Osslaught. The conversation devolves into conflict, where both Kazimir and Osiris are slain before the party manages to kill off most of the werebeasts, blowing up the hotel and escaping into the woods. Osiris is saved by a combination of magical energy from Yndra and Kira Delgado, against his wishes. Kazimir is offered a deal by the devil he had previously been tied to. If he would give this devil his body, the devil would allow him to keep his life for a period of time to accomplish his remaining goals. Kazimir accepted.
The party discovers that Kazimir is cursed by the werebeast disease, but the party cures him that evening.
After spending some time recuperating in Ectin Falls, Osiris leaves the party, headed to a confrontation with Yndra. The party is hired by the Shunt Mining Company to go and discover what is happening with one of their mining towns, Tenpenny. On the way the party discovers that Kazimir now has a devil riding around inside of his body, and they also meet a Goliath named Gor Iceclaw who travels with them, and a human named Shep.
Upon arriving in Tenpenny, the party discovers that the town has been overrun by demons, led by Kilvar, who is now called the Prophet. The Prophet reveals that there is a prophecy and that several members of the party are caught up in that prophecy. The party kills the Prophet, finally freeing Kilvar from the demonic entity. However, during the fight, it is revealed that Gor is working for The Spirited Mind, and a Mind hit squad comes into the town hunting Kazimir, or rather his devil passenger. Shep tries to turn the party against Gor, however the party sides with Gor in the confusion and Shep leaves. Gor, attempting to help free Kazimir from his devil passenger, casts a spell on Kazimir, flinging both Kazimir and the devil, a being known as Asmodeon, out of Kazimir’s body, also revealing that Asmodeon held a blood soaked piece of the prophecy, the sword, while Kazimir held a piece, the knife. During the struggle, Kazimir fails to regain his body and dies. Asmodeon regains control over Kazimir’s body and flees, taking the knife piece after Telos ended up with the sword piece. Asmodeon is captured by the Spirited Mind, but is then freed by Shep.
Gor is taken by the Mind hit squad after they fail to capture Asmodeon, and Telos and Thorin are left to head back to Ectin Falls alone.
During this time, Osiris is seen to be travelling to Wardvin, where he confronts Yndra. Angry with her, he uses a dagger he took from Kilvar to attack her. He is immediately possessed by a demon. His attack fails to kill Yndra and he is captured by her Marked guards.
The party reconvenes in Ectin Falls, where they meet with Asmodeon and three new people met along the way, Havok Gulbrand, Serico Mahn'davi, and Verboden. Asmodeon reveals that the party needs to collect the rest of the blood soaked pieces of the prophecy or the world will be overrun by demons. The pieces, Sword, Knife, King, Queen, and Fool, have found themselves together in the party except for the Queen. Telos, carrying the Fool and Sword pieces, gives them up to Havok, and leaves. The rest of the party travels to find the Queen piece. Along the way they meet a Half-orc by the name of Kon Kirak, who reveals himself to be Telos’ adopted father. The party fights the Spirited Mind hit squad once again, defeating them.
Telos, meanwhile, attempts a hostile takeover of the Rough Riders, the New Frontier’s lawmen. He fails, but still joins the Rough Riders. The party and Telos all find themselves at the headquarters of the Free Company of Brethren, where the Queen piece is revealed to be. A meeting is happening between several organizations, but the meeting dissolves into hostility and chaos. Telos kills his father Kon in the chaos, the party frees a collection of women and children, one of whom carries the Queen piece, and escapes, taking Telos with them.
The Queen, united with the other pieces, teleports the party just outside the town of Twin Rivers, where a portal to the Warrior of Light is. The Warrior of Light is the person they need to get the blood soaked pieces to. There they reconvene with Asmodeon, and discover that the town is home to a dwarf, Bjorn Bloodaxe, who had been Kazimir’s ultimate target, and the source of his unfinished business. Asmodeon, vowing to complete the prophecy and also to finish Kazimir’s unfinished business, leads the party into the town. There, they sneak into the mine, and find a creature called the Gatekeeper, and a reborn Osiris. Osiris tries to convince the party to turn back, but is discovered to be possessed by a demon. The party fights and kills Osiris and the Gatekeeper, opening a portal to a demiplane where the Warrior of Light is. There, they fight their way through an army of demons surrounding the Warrior of Light, who is barely holding the demons at bay. They are also joined by Fallon, an interdimensional hopping Bard. The party fights and kills a massive demon called the World Eater, along with a once again reborn Osiris in the form of a demonic death knight. The Warrior of Light, revealed to be Kira Delgado, Osiris’ old flame, is given the blood soaked pieces and returned to her full power. Asmodeon leaves, after getting the party to promise they would kill Bjorn Bloodaxe for Kazimir, stating that he had unfinished business in the 9 Hells. The party exits through a portal, and finds themselves on top of a mountain, face to face with the goddess Yndra herself. Yndra informs the party that the dragons had returned, and she needed their help to save Ryllian.
Discovering that the Spirited Mind had been a front for Dragons all along and that they had been the ones sapping the magic from the world in order to destroy Yndra’s banishment of them from Ryllian, the party returns to Twin Rivers. Verboden discovers that he remembers more and more of who he is, and that he is a dragon who had betrayed his kind for Yndra, long ago. Returning to Twin Rivers, the party fights and kills both Bjorn Bloodaxe, as well as a dragon.
The party travels back to Ectin Falls, and begins recruiting warriors to join them in the fight against the Spirited Mind, who is amassing an army in the Cursed Lands. The party recruits the Rough Riders, several mining companies, and joins with the Army of the Gods before taking the fight to the Spirited Mind. Fallon makes a deal with Asmodeus himself to bring Kazimir back to life, promising the souls of a large amount of people in return, or if unsuccessful, his own soul. Kazimir returns and joins the party momentarily before leaving to recruit his Artist’s Guild in the fight. Fallon enters the Dark Tower, a Spire in the Cursed Lands, meeting a wizard, and tries to get his assistance in the fight. The wizard gives Fallon a magic item, warning him not to take it out of his pocket.
The final confrontation occurs, and the party leads the army to victory over Nero the Necroblade, the leader of the Spirited Mind army, an old foe of Havok’s. Yndra thanks the party, recognizing Verboden, but he turns away from her, and she leaves him be. Fallon, having failed to fulfill his contract with Asmodeus due to the magical item in his pocket allowing the wizard to take the souls of the fallen instead of the devil lord, begins to be taken by Asmodeus but is instead taken by the wizard, who offers him a job.
The rest of the party scatters to their own business. Kazimir returns to the 9 Hells to seek out a way to rescue the soul of his friend Osiris, thus beginning a new journey.
