Ambālikā

Ambālikā was the daughter of king Kashya of Kashi. She was the sister of Ambika and Amba. Her hand was won in a competition by Bhishma and she married Vichitravirya, king of Hastinapura, along with Ambika. She was the mother of Pandu and grandmother of the Pandavas. Vichitravirya died without leaving children so the sage Vyasa, son of Satyavati (former queen dowager of Hastinapura) visited both widows and impregnated them with Vichitravirya's legal heirs. Ambalika was frightened of Vyasa due to his unkempt appearance and her son, Pandu, was born with a pale complexion.

After Pandu became king, Ambalika, along with Ambika and Satyavati, went to a forest retreat where they remained for their final days.
