Quests of Doom IV: War of Shadows (5e)
War of Shadows by Tom Knauss
War of Shadows is an 8th-level adventure that picks up where Between a Rock and a Charred Place left off. Erod Flan weathered the dark folk's storm¸ yet the conspirators are not done. Their focus now turns to the critical outpost of Tyr Whin. The PCs and the outnumbered defenders must somehow stop the hobgoblin warlord¸ Grugdour¸ and his army from overrunning the citadel and opening a beachhead for invasion into the Stoneheart Mountains.
