Mahmut, Erbach, and co. arrive at Chielo and meet the state-city's leader, Carvajal, and his secretary, Cassandra. With the Balt-Rhein army pillaging provisions around the surrounding areas, thousands of refugees come to Chielo (who has a strong welfare-based system) to seek aid and shelter. Despite this taking a toll of their food supply, Carvajal allows the refugees in and agrees to join the Anti-Imperial Alliance to safeguard Chielo. In Tauro, Halil meets with Blanca and Vasco, who privately shows him a blueprint of a weapon he designed. However, Halil refuses to endorse Vasco's weapon, fearing its mass destruction. Halil burns the blueprint before moving out his troops upon hearing the Imperial army speeding up their advance to Chielo, unaware that Vasco possesses a copy of his blueprint and still plans to avenge his people. As Chielo prepares for war and the Turkish army arrives to help, they cut off Balt-Rhein's supply route, causing them to rely on the sea route for provisions. During the transition, Mahmut and Erbach lead an attack on the 12th army division, who is in charge of delivering the supplies to the main army. After stealing some of the supplies, Mahmut's group lures the 12th division and another Corps division in Chielo and burn them alive. However, General Pineau halts the rest of army after Commander Johan Frentzen realizes that Chielo has set a trap within the city, leaving Chielo's militia outnumbered. Knowing that Chielo's entire plan was risky gamble, Pineau orders a full-out blockade around Chielo to lay siege upon the city, waiting for Chielo to run out of their own food supplies.

Mahmut y rencontre le directeur Carbajal, chef d’Etat de Chielo, et sa secrétaire Casandra.
