Storm Kings Thunder
Leader of Zhentarim Mercenaries
Xolkin led a group of Zhentarim mercs against the town of Nightstone. He later grudgingly allied with the players to help defend the town from invading orcs. After dispatching the orcs a letter was received from a halfling named Felgolos and Xolkin quickly got his mercs in order and attempted to chase after him.
Xolkin is a tall condescending man who is deep in the Zhentarims dirty dealings. He leads a mercenary strike team that is basically the muscle of the Zhentarim.
He is most known for his successful heists in and around Neverwinter.
