The village turns out to have a very helpful Witch Coven on the south side of town, who volunteers their massive cauldrons for the Soup Kitchen effort, promising that they have been thoroughly cleaned since the last potion-making effort.
The city isn't exactly large, only about five thousand people, but by rough estimate, they will need three hundred gallons of soup to feed that many.
"We need every large cauldron and oversized soup pot to the old Druid's tree as soon as possible." The mayor calls out, using a spell to amplify his voice.
Many adventuring groups carry a ten-gallon pot with them, so there are a number of them in town, as well as the ones owned by the restaurants. In theory, every ten-gallon pot will serve a hundred or more, and portions of magical beast meat are very filling, so they will need even less, with a single bowl a day being more than enough energy to keep most transfers going if the soup is heavy on meat.
