Vichitravirya

According to the Hindu epic, he is the youngest son of Queen Satyavati and King Shantanu, and the de jure grandfather of the Pandavas and the Kauravas.

Vichitravirya has an elder brother named Chitrāngada, whom his half-brother Bhishma placed on the throne of the kingdom of the Kurus after Shantanu's death; he is a mighty warrior, but the king of the Gandharvas defeats and kills him at the end of a long battle.

[2] When he had reached manhood, Bhishma marries him to Ambika and Ambalika, the beautiful daughters of the king of Kashi.

Subsequently, through a niyoga relationship with his half-brother sage Vyasa, his wives and a maid give birth to three children, namely Dhritarashtra, Pandu, and Vidura.

According to the Bhagavata Purana, he dies of a heart attack because of his attachment to his wives, Ambika and Ambalika.
