The dwarf Gundren Rockseeker hired you to escort a wagon of mining supplies to the frontier town of Phandalin, on the Sword Coast north of Waterdeep. He rode ahead with a warrior named Sildar — and now their horses lie dead in the road, black-feathered arrows in their flanks. Goblins. Your first adventure begins with an ambush, and ends wherever your dice take you.
