Vichitravirya

In Hindu mythology, the son of
Satyavati and king Shantanu. Vichitravirya dies after his marriage to
Ambika and Ambalika, but before he
has fathered any children. In her desperation to perpetuate King Shantanu’s lineage, Satyavati calls on her eldest son,
Vyasa, to sleep with the two wives. From
this union Vyasa sires Pandu and
Dhrtarashtra, whose descendants form
the major warring factions in the
Mahabharata, the later of the two great
Sanskrit epics.
