Chapter 6: Yatil Mountains

From the introduction:

As they begin Chapter 6 of the Great Flanaess River Adventure, the canoeing party faces the challenge of white water rapids while paddling down the Velverdyva Rivers. They gain a reprieve when they come to a rocky shelf where they can camp for the night. There, they discover a community of gnomes who welcome them in as guests. Like all gnomes, they end up needing assistance when attacked by a band of evil norkers. It is, however, the mysterious walled-up opening in one of the cavern walls that causes them to seek the party’s assistance. Will the brave party members enter the strange tunnels? And what lurks therein? Find out in Chapter 6 of the Great Flanaess River Adventure!
