Trader Scrit
Trade Boss Debslok, seeing that the locals of any region trade more among each other than with the actual traders came up with a scheme to get her hands on some of the local trade. She had a series of tokens crafted from various materials, and gave them to her most trusted traders to trade. Where these tokens went after the trade was of little concern for them. The traders get around and not everyone is wholly trustworthy, and for some things the traders would much rather not get their hands into.
When used with anyone in the Trader faction, they will accept this item at full barter value. Which means they won't apply their 'trade tax' to it, and it works for anyone who's part of the traders.
