In Anjou, you'll find the person you need at [address]. You'll deliver payment - I'll provide that, obviously - and obtain a number of boxes, fairly small in size. Most can travel in the cargo hold without difficulty. The last must be carefully kept clear of steel and water, or the results will be unpleasant, or so I'm told. You can have one of your people drop them at docks warehouse 707 upon return, then notify me. 2,000g upfront, 2,000 more upon return with the cargo.
