An Introductory Adventure for Storm King's Thunder. As evening approaches, you spot a wooden signpost next to a trail that heads north into the hills. Nailed to the post are three arrow-shaped signs. The two marked “Waterdeep” and “Daggerford” follow the High Road but point in opposite directions. The third, marked “Nightstone,” beckons you to follow the trail. If memory serves, Nightstone is roughly ten miles up the trail. This is Chapter 1 of the greater story available for free on the Dungeon Master's Guild.
