Osman Bey establishes an independent principality, celebrated with prayers and festivities in Yenişehir. Yakup Bey sees this as a challenge, questioning what his next move will be when facing Osman Bey.

A new threat arises with Gorklu Khan, an Ilkhanate emir aiming to marry the Byzantine Princess. This marriage could strengthen Byzantine-Ilkhanate relations and threaten the Turks in the Borders.

Osman Bey, aware of the danger and Gorklu Khan's hostility, strategizes to prevent the marriage and take Princess Maria, aiming to safeguard the fate of the Turks.
