Sack of Gasulta (5E)

From publisher blurb: A village in celebration, a sudden raid, and a desperate retreat to safety and fierce struggle to repel the invaders. Gasulta is a quiet provincial town, packed full with seasonal revelers and pilgrims. The party finds themselves in the midst of an unexpected and frantic raid and must fight their way to the keep- either fleeing for their lives or saving the townsfolk they can along the way. At the keep, the siege must be repelled- should its gates fall, whats left of the town will surely be slaughtered.
