Sithriss is a male tatzlwyrm living with his mate on the Skunk River. When first encountered by the party he was intrigued by the curious band of adventurers who decided not to immediately attack, but rather to talk. The party offered to trade some of their gems for some of his more useful treasures, eventually agreeing to purchase a cold iron longsword from the wyrm. They also agreed to let him keep his home on the Skunk River, free from any interference from the party.
