What is "shakuni"

Shakuni (, lit. bird) also known as Saubala ( Sanskrit: सौबल, lit. son of Subala) and Gandhararaja ( Sanskrit: गान्धारराज, lit. king of Gandhara), was the prince of Gandhara Kingdom in present-day Gandhara, later to become the King after his father's death and one of the main villains in the Hindu epic Mahabharata. He was the brother of Gandhari and hence Duryodhana's maternal uncle. Portrayed as an extremely intelligent but devious man, Shakuni is often credited as the mastermind behind the Mahabharata war. Shakuni had two sons named Uluka and Vrikaasur (Bhasmasura).

It is believed that Shakuni was the personification of Dvapara Yuga.
