Marya was a Greek girl and slave. She was bought by Ares, from slave trader Simko. Simko sells her so that she can spy on Ares. She betrays Ares by saving Ertugrul's son Gunduz and marrying Artuk Bey, but then betrays Ertugrul and Artuk Bey. She realizes that they know she is a traitor when trying to give the news. Then, when the Seljuks took over the castle, Sadeddin Köpek set her free and gave her to the Governer of Bilecik. He does that to tell the Governer about what has happened to the Kayis and Cavdars throught Marya. But then, Marya gets killed by the Governer because he knows what Marya has done.
