Samuel begins his career by performing fraudulent exorcisms on grieving families, such as the widow Lena whose rocking chair seemed to move due to a draft, allowing him to pocket easy cash without risk. This routine continues until he receives a call from his broker Q'Shar regarding a genuine haunting involving a woman named Sarah Willis who claims to smell burning hair and hears Black Speech in her nightmares. Unlike previous cases, this threat involves a real spirit capable of manifesting physical harm and projecting illusions into Samuel's mind during sleep. Samuel prepares elaborate magical gear including cursed talismans and holy water mixed with bone dust before confronting the entity in its lair. The battle escalates quickly as the creature attempts to trap his consciousness within a nightmare labyrinth filled with white mist and shifting geometry. Samuel realizes the creature is not a simple ghost but a spawn tied to a mana vein, forcing him to invoke a dangerous contract with Azathoth to summon eldritch tentacles from the void. He successfully defeats the beast using spatial manipulation and abyssal magic, marking the first time he uses true power rather than deception. This milestone establishes the central conflict where Samuel must balance his mercenary nature with the growing threat of supernatural resurgence. The victory proves that magic is returning but warns that using it attracts attention from both old enemies and new dangers lurking in the shadows.

Sam travels to Brazil to rescue Ophelia, a college student kidnapped by human traffickers working for a corporation mining Thunderium linked to a mana pathway. The mission involves infiltrating a brothel basement protected by armed guards and a resistant assassin who survives multiple spells due to a bloodline ability. Samuel utilizes his curse weaving skills to blind the target and employs a familiar summoned through astral projection to locate the victim's position. During the escape, he is ambushed by mercenaries hired by the Winser Clan who attempt to steal the mana vein information. After a high-speed car chase involving enchanted crossbows and motorcycle assassins, Samuel secures Ophelia and returns her to safety. Ophelia reveals she was chosen by a foreign deity associated with space and death, indicated by strange visions and a mark carved into her chest. Samuel recognizes her potential as a Sacred Warlock and offers her apprenticeship, integrating her into his operations. This arc highlights the geopolitical implications of magic returning, showing how corporations and clans vie for control over resources that could restore power to the arcane world.

Upon returning to the United States, Samuel focuses on securing the land surrounding the mana vein he discovered in Brazil, which is technically owned by ES Electric. He negotiates with the CEO Mark to purchase the property in exchange for returning his kidnapped daughter, leveraging the secret knowledge of the Thunderium mine. Simultaneously, he learns from Q'Shar that the Miracle Bringers, an ancient enemy group thought extinct since the War of Tears, may have resurfaced. Documents found in a safe reveal techniques used to create living curses and homunculi that mimic the methods of these historical traitors. Samuel deduces that the attacks on him were orchestrated by smaller families acting as proxies for larger clans interested in the vein. He decides to postpone retaliation against the Winser Clan until after the upcoming Common Sabbath organized by the Vatican. This period is spent consolidating resources, building relationships with other factions like the Norwegian sect of Ancient Trees, and preparing for a wider conflict. The stakes rise as Samuel realizes he cannot act alone and must navigate complex alliances to protect his interests.

Samuel undergoes a ritual to ascend to the third circle of magic, utilizing the mana from the defeated spawn and his new understanding of space attributes. He teaches Ophelia the fundamentals of spellcasting, emphasizing the difference between secrets and mysteries and how mana reacts to intent and emotion. The training involves meditation exercises and practical application of curses, preparing her for the dangers of the awakening world. Samuel also investigates the strange phenomenon where his judgment ritual indicates his orbit is incomplete despite having sufficient mana. This mystery suggests a deeper layer of magical law or interference that requires further study. Meanwhile, Ophelia begins to accept her role as a killer to satisfy her god's requirements, grappling with the moral weight of sacrificing Tom to save herself. The narrative concludes with the establishment of a new status quo where magic is slowly reintegrating into society, posing threats to the mundane population. Samuel prepares to face the Vatican Sabbath and the return of ancient deities, knowing that his path is one of constant conflict and discovery.
