Fantasy Flight Games continues expanding Descent: Journeys in the Dark Second Edition (designed by Daniel Clark, Corey Konieczka, Adam Sadler, and Kevin Wilson) with Guardians of Deephall, the forth release in the Hero and Monster Collections. Like the previous expansions, this requires the base game to play.

Guardians of Deephall will include four new hero figures and three new monster figure groups that were originally only available in the first edition of
Descent.
Two new quests will be included in the expansion as well.
The Curse of Iona takes heroes into an icy dragon lair to save the city from destruction and
Guardians of Deephall pits the heroes against an onslaught of undead at the city walls.
Components include four hero models, two crypt dragons, four dark priests, and three wendigos. Guardians of Deephall is expected to release in the fourth quarter 2014.
