What is "suktimati"

Suktimati (Shuktimati, Sukti) was the capital city of the Chedi Kingdom in India. It lay on the banks of the river Shuktimati flowing through Chedi. It was built by a Chedi king known as Uparichara Vasu. In the Mahabharata, it has been quoted that this river gave birth to twins(a boy and a girl) through its association with a mountain called Kolahala. The river then gives the twins to king Uparichara Vasu. King Vasu, makes the boy the commander of his armies and marries the girl, Girika.
