There is just nothing I have read about him that doesn't make me cry. I teared up at his wiki article for heaven's sake!

Speaking about wiki, wikipedia redirects Vrishali's name to Karna's entry and still won't tell me who she is. Google was also not very forthcoming so all I found out is that she was one of Karna's wives. So honestly, your series on the Mahabharata women? A gift to humanity.
