Liam arrives at Portal Home and steps into Ademia, where he joins a ragtag recruitment group known as the U-Nerds. Under the guidance of Major Pain, a seemingly lazy commander with a penchant for terrible puns, Liam is grouped with a bizarre squad of eccentric outcasts. This includes Elio di Fiore, a blind Italian Mage who took his blindness as a negative quirk to double his magical power, Ciara Doyle, a stoic sniper hired to be Elio's eyes, and a married podcaster duo named Nix and Haddock. Haddock is a builder who cannot use the system for permanent structures but can summon temporary walls, while Nix is a Mage who can only target areas with massive elemental forces like flash floods. Together, they venture out into the Killing Grounds to hunt Core Leechers, but their lack of coordination quickly turns their first excursion into a disaster. Elio behaves with supreme arrogance, treating the others like expendable tools, while Nix struggles with her high mana costs. When the monstrous Leechers attack, Liam is forced to act as the frontline tank, using his new Wave of Reflection talent to redirect damage back at the beasts. The battle escalates when Elio recklessly casts a massive Missile Storm directly on top of Liam to steal the kills, nearly ending Liam's life if not for Elio's companion Ciara Doyle helping pull him away and Haddock intervening with a temporary stone shelter. Though they survive the encounter, the betrayal is too much to bear. Liam confronts the blind Mage, flings him to the ground, and officially dissolves the partnership, choosing to strike out with Nix and Haddock instead. But as they begin their slow march back to the human settlement with their hard-won loot, a sudden, soul-rattling scream echoes across the flatlands, signaling that the safety they once took for granted is about to be shattered forever. They realize that the competitive nature of the other factions is the least of their worries, as the monstrous native inhabitants of Ademia are beginning to mobilize their forces for an all-out assault against the human interlopers.

The fragile peace of the human settlement is utterly destroyed when a massive army of Kadren monsters launches a coordinated assault on the Ever Steady. Led by a colossal, Level Thirty-Two Higher Skreeling, the beasts breach the stone walls, sending the defenders into a state of absolute panic. Liam and Elizabeth, a local alchemist, are caught in the chaos as they try to salvage healing supplies. The battle turns hopeless as the legendary human champion known as the Titan is brutally killed, leaving the frontlines completely exposed. The Higher Skreeling rampages directly toward Liam, who has no choice but to stand his ground with his battered bone shield. Using his Wave of Reflection talent, Liam absorbs the momentum of the charging behemoth, dealing a fatal blow but leaving himself on the very brink of death with only eighteen health remaining. He wakes up amidst the smoldering ruins of the camp to find Elizabeth dead and the human forces completely routed. The surviving humans are either slaughtered or captured by the Kadren to be kept as thralls through their unique slave bonds. Realizing that the Ever Steady has fallen, Liam is forced to flee into the wilderness, pursued relentlessly by a cunning, Level Twenty-Two Lesser Glimmerscale. The lizard stalks him through the dark, raining fiery missiles that slowly destroy Liam's armor and shield. Running on empty and suffering from multiple debilitating debuffs, Liam uses a desperate survival tactic from Earth, covering himself in freezing mud to mask his heat signature from the predator. He endures a night of agonizing cold, but the gamble pays off, allowing him to survive the night and unlock a rare version of his Self-Heal skill. As the morning sun rises over the foggy plains, Liam realizes he is entirely alone in a hostile world, and must find a way to grow stronger if he ever hopes to rescue his enslaved kin from the clutches of the monstrous horde.

Liam spends the next several days grinding for levels in the wilderness, targeting slow but deadly Vicious Millipedes to upgrade his defensive capabilities. He refines his passive combat style, learning to intentionally take poison damage to level his resistances while relying on his rare Higher Self-Heal to keep him healthy. After reaching Level Fifteen, he decides to climb a massive cliff face to avoid a guarded pass, utilizing his newly upgraded Climbing and Athletics skills to scale the vertical rock wall. Atop the ridge, he encounters Cuilcis, a golden-skinned Tibidi Crafter, and his mercenary escorts who immediately try to rob him. Using his newly maxed-out Wheel of Magic talent, Liam unleashes a relentless barrage of elemental missiles, killing the mercenaries and forcing Cuilcis to surrender. Recognizing the value of Cuilcis's vast hoard of knowledge, Liam spares the merchant in exchange for safe passage to Last Chance, a lawless shanty town of outcasts and exiles. In the city, Liam manages to rent a secure room, soak in a magical bath, and strike a deal with a legendary Larian smith named Stalwart to craft a custom steel tower shield. To secure the materials, Liam leads a collection team into a nest of cute but deadly Lyrian Rastlers, who spit potent acid that dissolves his remaining armor. Liam endures the agonizing burns, using his Wheel of Magic to wipe out the beasts while the collectors gather the precious acid alloy. Upon returning to the city, Liam is reunited with Nix, Haddock, and their new Canadian companion Steve, who has a powerful invisibility talent. Just as they celebrate their reunion, a massive shadow falls over them as an enraged, four-armed Gold-Rot Fighter named Adrasteina storms the tavern, seeking to murder Cuilcis for his deceptive trades and threatening to destroy anyone who stands in her path. The confrontation escalates rapidly, forcing Liam to step in as the protector of the town's most valuable knowledge source.

Liam and his team are forced into a brutal battle against Adrasteina, one of Last Chance's absolute untouchables. Haddock quickly reshapes the battlefield, creating a deep earthen pit to trap the four-armed warrior, but her immense strength and high-level defensive talents allow her to shrug off their initial attacks. She launches a relentless flurry of punches, bypassing Liam's shield and nearly beating him to death with her overwhelming power. In a desperate bid for survival, Nix uses her new Earthen Gauntlet talent to summon a giant clay hand that grabs Liam, physically maneuvering him to block Adrasteina's blows while Steve strikes from invisibility. Nix then unleashes a Delayed Firebomb directly into the pit, engulfing both Liam and Adrasteina in a massive explosion. Though Liam suffers severe burns, his double Fortitude and passive resistances keep him standing, and the combined damage allows his Wheel of Magic to finally put the untouchable down. The victory earns the team massive experience, propelling Liam to Level Twenty-Five and unlocking the Passive Specialist class evolution. With his new Mirror of All talent, Liam can now project his immense Fortitude to manipulate the emotions of his enemies, turning their anger into an unstoppable taunt. The team blackmails Cuilcis into teaching them the secrets of higher-rarity skills, allowing Liam to upgrade his Shield, Running, and Self-Heal to rare status. Armed with a newly crafted steel tower shield and a powerful plan, Liam leads a pack of fifty Kadren monsters directly to the gates of Last Chance, using them as a distraction to unite the lawless factions. He prepares to launch a daring rescue mission to free the thousands of human slaves held in the Kadren pens, turning the tide of the war and establishing humanity as a force to be reckoned with. The stage is set for a massive clash of civilizations, as the passive-aggressive hero prepares to strike back at the monstrous overlords of the Torn Divide.
