Image: Rebel Wolves / Bandai NamcoNo screenshot of Nish yet. This one shows Svartrau (Rebel Wolves / Bandai Namco).
Nish is a vrakhir hiding in Svartrau whom you track down in Lacra's side quest A Friend Like This. You have to win the first fight, but you can talk Nish down instead of killing.
Nish is a vrakhir Lacra wants found. Nish isn't happy to have company and fights first, asking questions later.
After the fight, the least violent path is to talk. Explain the situation, point out that Brencis is your common enemy, give your word and say you won't kill. The quest pays about 150 XP.

Lacra is a vampire who says she was sent to get rid of Brencis. She can become one of Coen's closest allies and a romance option, but she follows her own agenda.
The Matriarch
The Matriarch leads the Bakr clan, the Uriash who live hidden in the mountains. You reach her with Lacra in Song of the Mountain, and afterwards she sells witchcraft skill manuals.
