Mayor of Silver Falls
Gurrak was a driving force in letting the non-dwarves settle among the dwarves of Silver Falls. He did not do this out of any sort of compassion for the “surface races”, rather he used them as a bid for power and wealth. By opening the doors to the other races (and letting them know about his involvement) he was able to receive the support he needed to claim leadership of the city and the power and wealth that follows.
Gurrak is interested in wealth, both for the city but primarily for himself. While he would deal with just about anyone who can increase the wealth of him and his city, he is not however, stupid, and would not jeopardize the safety of his citizens directly nor his own position as their leader.
