Adventure Overview
The ice troll Frostbeard has discovered the Veil of Winter, an ancient artifact dedicated to the deity of frost, and is using it to expand the icy domain of the Azure Spine Glacier. This is causing frigid air to roll down from the Morrow Peak mountains into surrounding villages and towns. This is not only affecting the inhabitants of those towns, but also disrupted trade routes in the region. Inhabitants in the area believe another ice age is upon them and are seeking someone to stop it.
