From back of book:
Hall of Judgment is an adventure designed for the Dungeon Fantasy Roleplaying Game by Steve Jackson Games.
Deep in the glacial peaks northwest of Isfjall, past the northwest border of the realm, a band of adventurers is deceived and nearly destroyed by a powerful Alfar sorceress as they pursue raiding stóralfs. Through bravery and sacrifice, they retrieve and return a lost holy relic. The Tiwstakn: key to finding the legendary Hall of Judgment.
With most of the hajarl's warriors and freeholders out trying to restore order to Norðland, a priest of the God of Law calls for stalwart thegns to venture into the Frostharrow, rediscover the Lost Hall, and return balance to the land. They must journey into the wilds, guided only by their wits, old legends, and a warning: Strength and Sacrifice from those who seek the Domstollinn.
