Making a deal with a Goblin King

Sir, the cargo you ordered be sent to Sagarika has been detained and impounded by the Goblin King west of the Barren Mountains. As I have repeatedly advised, the King possesses far greater wit than you give him credit, and our deception as to the quality of the goods we were sending failed to dupe his staff. I will state once more for the record that I believe the only way to secure a long-term overland route through this region is free and fair negotiation with His Majesty. This will no longer be an easy task.
