Half-Fiend seems unlikely though, since that would probably give her demonic bat wings instead of angel-style white feathered wings. Perhaps she's Half-Celestial as I suspected, with the alignment details waived for Rule of Cool.
That'd still require that A. a celestial had sex with Duv's other parent and yet B. she was raised the loyal daughter of a pantheon of evil gods. And given her mission statement and her belief that her template was granted by her god as a blessing, a refluffed Half-fiend or Thuntemplate is more likely than half-celestial.
After all, Erinyes have feathered wings, and Malgubliyet's right-hand guy lives in Baator.
