Hello! While it's not impossible for Ciri to sell an animal part here or there to a few shops in Cadens, she should avoid doing it too often or making it known widely. Nocwich prefers to handle the exporting of its unique resources and goods to the other nations, since this is one of Nocwich's main advantages. Ciri is not a citizen of Nocwich, so any profit or benefit she gains making a business from the resources of their land would not go to them. Essentially, she can occasionally sell a part or two as a "favor" to someone in Cadens, but they'll notice if she consistently comes only to hunt in their woods and bring home game to sell.

They would be more accepting of her bringing items from Cadens to sell to those in Nocwich as long as it's not too much. She would not be able to do this in the Square, where all merchants are granted a permit and handpicked. However, as Luna will soon be available for the Summoned to visit regularly, similar to Oleuni Square now, she can sell to native residents in town who make a request.
