Barbaros Hayreddin Sultanin Fermani

The sons of the conqueror of Lesbos; Ishak, Oruç, Hizir, and Ilyas, were separated after the death of their father. Oruc and Ilyas sailed to the seas despite the opposition of their elder brother. Ishak is very happy that his brother is in his hometown, but Hizir also has in mind the great and sacred "secret" that he pursued. However, they are not the only seekers of this sacred secret.
