Mistbound

Publisher's blurb: Your party, on a routine adventure, finds themselves beset by a strange mist in the forests near Waterdeep. Wandering in circles, you eventually find the town of Welshire. The town is quiet and the townsfolk seem to have lost the will to live. The only way for the party to escape is to wait for the morning sun to temporarily banish the mist. However, leaving isn't the hard part; surviving until morning is.
