Welcome back to Neverwinter! Bards sing tales of heroes in ages past, but they rarely mention those that are yet to become heroes. One such hero is a farmer in the small village of West Harbor. Raised by the elven ranger, Daeghun, as his own child, our hero will embark on a grandiose quest against the King of Shadows. Neverwinter Nights 2 is the tale of his deeds. His adventures continue in Neverwinter Nights 2: Mask of the Betrayer. Our protagonist discovers that an ominous spell has fallen on him. A curse of perpetual hunger--one which can only be quelled by consuming the souls of spirits. In order to remove the curse, he has to travel to the Shadow Realm, which harbors dark secrets and tormented souls.
