Vin is the descendant of the line of Moltor who first met the blackburrow gnolls. His only remaining heirloom it would seem is a paw (container) whose magical properties are activated by a number of rings. He will apparantly be willing to part with this paw in return for 3 bottles of Khalish and a rat meat pie. (Apparantly there is no accounting for taste)
His father too apparantly valued alchohol more deeply than magical paws, as his father apparantly financed a trip to Odus via the rings that used to be attached to the paw.
For budding alchoholics out there, Odus is also home of some excellent distillers.
