Assault on Santa's Workshop is a Daggerheart-compatible adventure designed for a party of Level 1 characters. The main adventure can be played in a single session, with side quests and encounters stretching it into multiple sittings. Included with the adventure is the Treason's Greetings campaign frame. Can your party wrestle control of Santa's Workshop from the threat of scheming dark elves, entranced helpers, and murderous Christmas constructs?

The adventure takes the party to the small town of Dierbin. This frozen hamlet is located near the entrance to the demiplane that Santa's Workshop calls home. Currently, the town is also home to Santa himself. After being deposed by members of the Cult of Krampus posing as his elven helpers, Santa waits at the pub for the right team of adventurers to help him take back his workshop by force and save Christmas for good.

The adventure begins in the town of Dierbin, but the bulk of the adventure takes place in and around Santa's Workshop. Assault on Santa's Workshop can be completed in a single evening, but there is optional content in the town of Dierbin that can fill multiple sessions before the party makes the trek to the Workshop. Players can investigate mysterious webs of ice in the trees outside of the town, track down rumors of cult activity within Dierbin, or even get in a bare-knuckle brawl in the underground fight club beneath a treat shop known as Mama Sugar's Sweetery.
