Sarthaxx was a young white dragon. He had organized a variety of kobold tribes together and was directing their attacks against the outlying farms and merchant trains coming down the Coastal Trade Route.
The company infiltrated his lair, defeating his kobold minions and slaying him as one of their first notable feats in this region. With his dying breath, he swore that it would not end with his death, but that his father would avenge him.
Along with the various minor treasures found in his fledgling lair, the company found a scroll heavily covered with script in an unknown language.
