Nars Drendar

From Adrian's Persons of Interest:
Bjornar "Nars" Dendarr is the son of the Dendarrs of Phandalin. He was kidnapped from Faerun by the Werewolf Kiril. We met him in a tavern in the vicinity of Phandalin, Wyvern Tor. Sontehill Inn? It seems so long ago. Kiril pretended to be a Werewolf hunter of all things, Kai was tipped off to his identity but forgot his notes. He now probably resides in the mountains up in the north. From Ismark's vision we learned some of the captive children were being kept alive, for what reason?
