Viorr, of Breland’s Dark Lanterns (a branch of the King’s Citadel), commissions the Scouts to retrieve a rogue undercover agent Lucan who has stolen an item called the Soul Sword. Upon catching up to Lucan the Scouts discover that he has been turned into a vampire. The Scouts chase Lucan across Brelish and Zilargan landscape, a diplomatic masquerade party in Trolanport, a catastrophic elemental coach wreck, and into an ancient goblinoid Ziggurat. In the end Lucan’s course results in his sister’s Grilsha’s death, but the Scouts were able to disarm Lucan from the Soul Sword and talk him into peaceably returning to face the Dark Lanterns. Lucan appeared to be controlled by the Karrnathi Soul Sword as well as someone called Calderus.
