The Summerhill Wolf Pack is a pack of intelligent wolves led by two massive alphas, Fang and Claw, who were once regular wolves before the dark wizard Therrin Redwald implanted human souls into them.
The two escaped the wizard's clutches along with their brother, Tooth, and took control of the local pack, teaching them coordination and even a small sampling of common. The pack began to raid Summerhill for supplies and food to provide for the growing family, leading to the demise of Tooth.
The guild was brought in to eliminate the pack, but discovered their intelligence and the origins of the two remaining alphas. The adventurers eliminated the dark wizard who caused their transformation and brokered a peace between the pack and the village.
