Retrieve the Rare Hides.
I have a stash of extremely rare leathers, or... rather, I did.
A group of thieves must have heard how valuable my collection was because they stole it!
And THEN they had the audacity to leave a note offering to sell it back to me! As the "former owner", I'm able to "best appreciate the value of their new acquisition."
The note states they'll be waiting in the foothills behind the castle, to the east, until they find another buyer.
However you get the skins, consider them yours.
