As food supply dwindles you're forced to cook with more and more spoiled ingredients. Leading to sickness and hallucinations on top of the strange supernatural influence. Sleep won't come any more. Whatever is on the ship makes it impossible to rest. Vision is blurry and hearing is off. Which voices are real, which are the ghosts, which are purely your own? The wind has stopped and the ship hasn't moved is a week as the waves rock. People who you thought had jumped overboard are back making requests for dishes from their childhood. Spices you don't remember stocking and couldn't possibly be on board turn up in unexpected places. This looks like saffron. Does saffron taste like that all the time or is this something else entirely?
