re: Vrishali, there isn't very much information available about her; she's barely a step above Unnamed Wife of [insert hero]. She's Karna's chief wife, possibly the mother of all/most of his sons (many of whom are also Vrisha-something-or-other), and from a mixed family like his adoptive parents. She's also praised by Duryodhana and Gandhari, which is a bit of a rare combination and I think most of us latched onto.
