Baraek Brigson is a fur trader in the Varrock Square (the centre of Varrock). He will purchase bear fur for 12 coins each. If you choose the option that his price is unreasonable, he will pay 18 coins each. If players are wearing the ring of charos (a) he will pay 20 coins each.
If players have unnoted grey wolf fur in their inventory, a new option will appear when talking to Baraek - "Would you like to buy my grey wolf fur?". He will buy them for 120 coins. If players are wearing the ring of charos (a), he will be persuaded to pay 150 coins per fur.
Baraek is also a member of the Phoenix Gang and plays a small role in the Shield of Arrav quest. If players wish to be in the Phoenix Gang, he must be bribed to reveal the location of their headquarters.
If you try and haggle with him he claims he has a family to feed, but in the Varrock Census there is no other person that has the last name "Brigson". The Census is 10 years out of date, though, so it may be that he has obtained a family within those 10 years.
