Soren awakens to find an assassin looming over Ethea's bed. In a desperate lunge fueled by his newly ignited power, he intercepts the blade, taking a poisoned wound to his arm. The intruder flees, but the encounter triggers the Investment Authority for the first time, granting Soren the Ice Emperor's Legacy and seven other returns. He discovers his ability to sense Ethea's condition through Investor's Eyes, learning the horrifying extent of her curse and her 8-to-14-month death sentence. That same night, he begins cultivating the Glacial Emperor Scripture, breaking through to the First Circle in a single session, a feat that should be impossible for a newly awakened. The next morning, he feeds her breakfast with gentle hands, and she speaks her first words to him, a whispered request to be left alone.

Soren registers as a Bureau hunter and trains under Marcus Varn, learning basic spearmanship. His first solo Gate clear against Azure Slime Forest nearly kills him when his Frost Palm Strike backfires, but he emerges victorious with a boss core and a deeper understanding of his limits. He joins a party led by Darren for a raid on Moss Hollow Cave, where an ambush by an Elite Moss Creeper nearly wipes the team. Soren's quick thinking and Quick Step technique save Nina's life, earning the party's gratitude and a damaged variant core as reward. The raid solidifies his reputation as a reliable teammate, but also exposes him to the brutal reality of Gate combat, where one mistake means death. He returns home exhausted but exhilarated, his bond with Ethea slowly thawing as she begins to smile while watching him train.

During a Bureau-assigned mission to supervise academy students, Soren is drawn into a Golden Gate, a legendary treasure rift. He rescues a bullied student named Ryan and confronts the arrogant Garin Vale, who tries to kill them both. Inside the golden realm, Soren meets the Sunless Emperor, a spectral entity who tests his resolve and grants him the truth about Ethea's curse: it is an Eighth Circle malice that requires a master cursemaster or the curse's source to break. The Emperor also binds Soren to guide Ryan, the chosen successor. Together, they fight through a Third Circle Gate filled with Drakelings and a King Drakeling boss, combining their powers in a desperate final strike. Soren collapses from the strain, his body nearly destroyed, but they emerge victorious.

Soren wakes in a hospital bed to find Ethea holding his hand, her silent vigil revealing her deepening feelings. He learns that Garin Vale has been arrested for attempted murder, but his family has been systematically trying to silence Soren through assassins and legal pressure. With the help of Seria and the tactical recorder from the Gate, Soren presents irrefutable evidence in court, ensuring Garin's conviction. However, he also discovers that Garin's father, Ziso Vale, is a cold, calculating 5th-circle hunter who has already cut his son loose to preserve the family name. Soren realizes that a third, unknown party is manipulating events from the shadows, separate from Ethea's original enemies. The trial ends with justice served, but the true war has only just begun.
