The party located Veram in the underground complex, about to be sacrificed by a serpent like people. Killian was able to exchange his father's sword for Veram. A heavy price, but worth it f they could gather intelligence from their captive. Oloril seemed to have other ideas, however, nearly killing Veram. Questionable? Yes. Out of character for Oloril? Not necessarily. Roscoe made a strange request of Veram, asking him if there was something he wanted to show him? A symbol or badge of allegiance perhaps? Odd indeed.
Needless to say the party was attacked on their way back to Waterdeep - by a dragon. And, as fate would have it, Veram was stolen away. Was anything gained from Killian's exchange? Perhaps not . . .
