The Singing Mercenaries
Kalarel was the nemesis of the Singing Mercenaries when they campaigned in the town of Winterhaven. Master of a death cult of the Demon Prince, Orcus, Kalarel was defeated by the Singing Mercenaries in the depths of the Keep of the Shadowfell. Kalarel had employed goblins and even more unsavory types in order to safeguard Shadowfell Keep, however the mercenaries managed to fight their way to its very foundations, discovering Kalarel’s obscene ritual to bring his dark master into the world through a rift in the Shadowfell. Kalarel was defeated, and his magical rift was sealed just after Kalarel himself was sucked into it. He was last seen being devoured by an otherworldly creature, screaming promises to return and have his revenge. The events that transpired in the Shadowfeel Keep can be read here.
Despite his apparent demise, Kalarel’s reach seems to extend beyond death. His cultists, or at least crazed bandits and mages bearing his cult’s mark, have recently been killed by the Singing Mercenaries along the trade road from Fallcrest to Hammerfast. Other cultists and even risen spirits have also proclaimed his return. It remains to be seen if his reach is indeed as long as he promised.
