Jak

Jak is a travelling merchant that resides in Traveler Town, and has ridden with them for the past two years. His mount is Carl, a camel that lost its back legs in a fight with a daggerclaw in the Talenta Plains and has since been modified with a cart that also houses Jak's goods.
The gregarious merchant claims that his persona was a dear friend of his, and a well-known merchant in the Talenta Plains near Gatherhold. He travelled from that region at the end of the war, trading for goods along the way, until he came upon the wandering tribe of changelings near Tower Vigilant. He has been their merchant ever since.
