Chapter 1: Blackmoor

From the introduction:

Growing up in the Village Arneson, situated in Blackmoor, at the headwaters of the River Fler, you and your friends have long desired to visit the Gem of the Flanaess – Greyhawk! Having finally decided to gather together as an adventuring party, you set for yourselves a simple goal: Take to the river in canoes and paddle to the City of Greyhawk - or die trying! It is time to prepare for the journey: crafting canoes, hunting for food stores, and raising funds for supplies. Once all the preparations have been made, that fateful day will come, when you launch your canoes in the river and begin the journey of a lifetime.
