Orhan Bey continues his nine-year siege of Bursa to fulfill Osman Bey’s vision, facing formidable resistance from Saroz and Flavius. As tensions rise, Osman Bey convenes a council that could decide Bursa’s fate, with Şahinşah Bey challenging Orhan’s command and Alaeddin Bey offering himself as an alternative. Amid political turmoil, Nilüfer Hatun stands by Orhan with unwavering support, while Malhun Hatun, losing hope in Gonca, seeks a new bride for Alaeddin. Orhan escalates the conflict by killing Flavius’s brother, prompting a vow of revenge and setting the stage for a storm at Bursa’s gates.

Orhan Bey returns victorious but is shaken by unexpected news, prompting him to surrender his position to Osman Bey with a solemn acceptance of fate. As tensions rise between Alaeddin and Orhan, Temurtaş's secretive alliance with Saroz and his hosting of Şahinşah and Alaeddin deepen the intrigue, especially as his schemes leave Osman Bey bedridden. Orhan faces mounting pressure from Byzantine and Ilkhanate forces while striving to fulfill his father's dream of conquering Bursa, where he confronts the vengeful Flavius in a deadly bid to rescue Boran. Meanwhile, Temurtash Noyan’s arrival threatens to upend the regional balance of power. Nilüfer Hatun’s belief that Orhan has been wronged sparks conflict among the women, potentially pitting her against Gonca and drawing a decisive response from Malhun Hatun. In a final blow, Osman Bey reclaims command of the siege and appoints Şahinşah Bey as leader, sidelining Orhan once more.

As the Byzantine, Ilkhanate, and Turkmen forces unite to defend Bursa, Orhan Bey urges diplomacy to dismantle the alliance, clashing with Şahinşah’s call for immediate attack despite Osman Bey’s illness. Tensions rise in the council and within the family, as Malhun Hatun fears division among her children, especially with Gonca believing Alaeddin deserves leadership while Didar claims Malhun favors Orhan. Meanwhile, enemies Temurtash, Saroz, and Flavius plot a devastating strike on the Kayı tribe, targeting a caravan led by Fatma Hatun. Driven by vengeance, Flavius seeks to capture her, but Orhan Bey confronts him head-on, determined to fulfill a hidden purpose in their fierce showdown.

Orhan Bey faces a critical test of leadership as tensions rise within the Kayı tribe, challenged by both his father and brother to prevent internal division. Supported by Nilüfer Hatun, he survives an ambush with help from Kan Turalı and Abdurrahman, then seeks to lift the siege of Bursa by negotiating with Temurtaş, risking confrontation with Alaeddin and Şahinşah Bey. Meanwhile, Flavius plots revenge in Söğüt, torn between attacking and protecting Fatma Hatun. Temurtaş’s brutal raid on Yarhisar leaves the tribe mourning, prompting Malhun Hatun to confront Alaeddin Bey. Despite Orhan’s efforts to stop the war, Alaeddin orders him to Karacahisar; when Orhan refuses, their conflict erupts into violence, leading to Orhan’s exile and a deep fracture in the tribe’s unity.

As Orhan Bey assumes leadership, unrest brews when Şahinşah Bey, angered by his removal from command despite pledging allegiance, seeks to challenge him. Determined to prove himself, Orhan Bey plans with Abdurrahman and Kanturalı to retake Yarhisar and honor fallen martyrs, marking his first true test. Meanwhile, Flavius, thwarted by the destruction of the Bursa tunnel, turns to violence, plotting an assassination against Osman Bey during Orhan’s sword-girding ceremony. With obstacles cleared in the camp, Orhan Bey advances his ambitions, seizing Bursa and issuing his first threat to Iznik, setting the stage for a new era defined by his uncompromising stance against the Tekfur.

Orhan Bey’s campaign to win Bursa blends mercy and strategy, alarming the Byzantines while a hidden threat rises in Söğüt. Flavius entangles Fatma in his schemes, suitors stir tensions in the camp, and Şahinşah’s loyalty is questioned as Temurtaş is courted. The Emperor’s sudden arrival with a mysterious woman promises to upend the tribe’s balance of power.

The Knights of the Holy Temple launch a brutal crusade in Anatolia, targeting Orhan Bey and his family, with Hector plotting to capture Fatma Hatun. Orhan and Flavius form a tense alliance against them, while Dafne’s arrival unsettles the Kayı tribe and sparks conflict among the women. Amidst forbidden love, marriage disputes, and rising tensions, the knights strike again—forcing Orhan to confront their relentless threat and leaving Fatma’s fate tied to whether Flavius reveals his true identity.

Orhan Bey’s rescue mission for Fatma Hatun is disrupted by Princess Asporça, who demands his father’s surrender and threatens war, while the Knights Templar attack, leaving him trapped between enemies. Flavius rescues Fatma and Yiğit, raising suspicions of secret alliances and prompting Daphne’s betrayal to Hector. As the tribe questions the true identity of the merchant Akçora—revealed as Flavius—Fatma and Alaeddin Bey uncover the Templars’ hideout in Söğüt, cornering Daphne and escalating the conflict.

Orhan Bey thwarts the Knights’ ambush on Princess Asporça, sparking new tensions in the camp and raising questions about his true motives as he maneuvers against Hector. Meanwhile, Hector orders Flavius to commit a killing that clashes with his love for Fatma Hatun, forcing a painful choice between loyalty and affection. Away from the tribe, Dursun and Halime confront their growing feelings, uncertain of their future. As conflicts mount, Orhan continues battling the Knights while advancing Osman Bey’s dream of raising the Kayı banner in Bursa.

Orhan Bey’s triumph over Hector reshapes the balance of power, even as he returns to camp to face the sorrow of Osman Bey’s decline and renews his vow to conquer Bursa. Asporça’s unexpected choice to stay and her bold offer deepen the political tension, while Flavius’s quest for revenge and his hidden identity push him toward a dangerous reckoning that threatens his bond with Fatma Hatun. As Bursa is finally taken and Osman Bey dies with its soil in his hand, an era ends and Orhan Bey steps into leadership, setting his sights on new conquests along the path to the Red Apple.

Orhan Bey’s conquest of Bursa sparks both the birth of a state and fierce opposition, with Karasid leader Demirhan Bey emerging as his most determined rival, refusing to yield the city’s future. As Orhan strengthens his hold on Bursa, a dark alliance of Mabedists, Demirhan, and Temurtaş plots to assassinate Asporça and frame him, risking a new war with Byzantium. Personal tensions rise as Halime and Dursun’s forbidden love edges toward exposure, Fatma reels from Flavius’s true identity and lashes out in heartbreak, and Şahinşah Bey maneuvers against Temurtaş’s schemes. Ultimately, Orhan Bey confronts growing threats by declaring his sultanate, marking a decisive turning point that reshapes the frontier world.

Sultan Orhan’s clash with Temurtaş triggers rebellion, shifting alliances, and rising intrigue, while Asporça’s unexpected turn against him and Nilüfer Hatun’s growing hostility deepen the turmoil. As Orhan rallies his forces after proclaiming his sultanate, he must navigate betrayal and looming conspiracies to secure his rule.

Sultan Orhan’s advance toward the Biga Gorge sparks unrest, pushing Demirhan to pressure Dursun into betraying him to save Temurtaş, while Nilüfer Hatun and Asporça’s clash deepens tribal fractures. As Şahinşah quietly maneuvers for power through Fatma Hatun’s engagement—forcing Flavius into a painful choice—Orhan’s negotiations in Constantinople take a shocking turn when the emperor demands he marry Asporça, whose growing fury now drives her toward thoughts of Orhan’s death.

Bursa is thrown into turmoil as hidden forces move against Sultan Orhan, while Asporça—angered by political schemes and Orhan’s secret İznik plans—launches open rebellion, ordering Nilüfer Hatun’s abduction and attacking Orhan’s soldiers through Flavius. Nilüfer is shaken by the emperor’s marriage plans, Demirhan allies with Germiyanoğlu Mehmet to weaken Orhan and target Alaeddin, and Dursun’s betrayal leads to his imprisonment and Halime’s desperate attempt to stop his escape. As Şahinşah joins Demirhan and Yiğit confronts his father’s corruption, Orhan prepares to face a tightening web of enemies on all sides.

Sultan Orhan marches into a decisive battle against Asporça, unaware that Shahinshah’s suspicious disappearance may signal a new betrayal. On the road to Germiyan, Alaeddin and Gonca narrowly survive an ambush while trying to protect their unborn child, and years later their encounter with Mehmet Bey will spark new turmoil. In Bursa, Demirhan reveals Dursun’s true motives, forcing Orhan and Halime into a painful reckoning. Asporça, wounded and vengeful, launches a new plot to capture Nilüfer and corner Orhan, while Flavius—torn between love and loyalty—falls into Orhan’s hands and faces judgment. With enemies closing in on every front, Orhan must confront treachery, war, and impossible choices.

Orhan Bey races to seize key territories while Şahinşah plots to kill Demirhan to protect his secrets. Nilüfer is captured and used as leverage by Asporça, leading to a bloody confrontation that endangers her life and unborn child. As alliances shift and betrayals surface, Alaeddin and Gonca struggle to escape enemy lands, and in Bursa, Yiğit’s jealousy over Fatma and Flavius erupts into violence, leaving him stabbed and threatening to expose their forbidden love.
