Neverwinter Nights 2: Mysteries of Westgate Hands-on

It starts with your ship arriving at Westgate. The first mate wakes you up to tell you that they're approaching the harbor. After a brief exchange of dialog, he stops talking, no matter what you say. He stands there strangely silent and unresponsive. A couple of winged demons appear and the first mate's eyes go red and menacing. Something is terribly wrong. And then you wake up for real. An unassuming cloth mask you've found had "turned sleep into sweat-filled torture."
