By this time, the relationship between Güyük and Toregene had deteriorated significantly, despite Toregene's role in Güyük's accession. Against Toregene's wishes, Güyük had Toregene's favorite, Fatima, arrested, tortured and executed for bewitching his brother Koden (Khuden), and Abd-ur-Rahman was also beheaded for corruption. Of the provincial officials appointed under Toregene, only the Oirat official Arghun Aqa remained. Toregene herself died later, possibly at Güyük's orders. Güyük had Temüge's case investigated by Orda Khan and Möngke, and they had him executed. Güyük replaced the child khan Qara Hülëgü of the Chagatai Khanate with his favorite cousin Yesü Möngke to secure his position. He also restored his father's officials, Mahmud Yalavach, Masud Beg and Chinqai to positions in the provinces.
