Terronoth's heroes confront some of the Overlord's deadliest minions within the confines of a haunted mansion in Manor of Ravens, an expansion for Decent: Journeys in the Dark Second Edition. Desperate bandits, terrifying wraiths, and a new lieutenant flock to the Overlord's aid.

He also gains a servant-a creature that can be summoned into play. Against these threats, two new heroes step forward, bringing new tactics along with two new heroes classes. Finally, six new quests allow players to uncover the Overlord's plans and confront entirely new perils.

The Overlord gains two new monster groups, a deadly new lieutenant, and his first servant-the Raven Flock. Six new quests can be played individually, woven into other campaigns with Rumor cards, or played as a mini-campaign telling the tale of the haunted manor.

Hero players gain two new heroes as well as hero classes for Warriors and Scouts-Marshal and Bounty Hunter. New Relics offer powerful effects, including relics that can be wielded by monster groups.
