From the introduction:
Navigating the Nyr Dyv, the adventurers move ever closer to their final destination. If they can survive the sometimes violent weather and the always violent creatures of the deep, the player characters will find themselves under watchful eyes as they round the Cairn Hills peninsula. Then, upon entering Midbay, they will discover that while the bay may be calm, what lurks in the sky is not (It’s not called Dungeons & Dragons for nothing!). From there they will enter the last leg of their journey – the Selintan River. Can the player characters survive the creatures of the deep? Will they discover the ones who watch with evil eyes? And will they make it to the mighty Selintan River alive? Find out in these very pages: Chapter 14 of the Great Flanaess River Adventure!
