    • There is a secret box under the carriage at the inn containing 500gp.
  1. The Sneaky Duck Inn, located in Blabourrough, used to be a thriving port of trade, frivolity, and meetings of beautiful friends. Some years ago the inn was burned down in a mysterious crime of arson. The culprit was never caught.
