On the First Night

From publisher blurb:

This festive adventure pits a horde of goblins against an evil, fire-breathing raindeer riding, elf from the northern wastes named Eothanta. The PCs play as a band of goblins sent on urgent missions by their dark goblin lord Grapfrut. The adventure includes riddles, combat, social role-play and some evil princesses.

The adventure is system agnostic and can used in any system as no stats are included. Several unique to module rules exist in this module - such as a the card game North Pole which uses dice, or the flight of the goblin war-ball, which also utilizes a bespoke d6 system.
