Kalarel's Revenge
The hobgoblins were not the only forces that remained after Kalarel was slain. Before the Keep’s portal was fully sealed, evil spirits from the Shadowfell escaped into the Nentir Vale. They were drawn to Kalarel’s own dark soul, which remained in the mortal world thanks to a spirit-orb the priest had created to prevent him from moving on after death.
The presence of these malignant spirits caught the attention of a frost witch called the Rime Mistress and her followers—unaligned territorial beasts—who rose up to defend their domain. The Rime Mistress knows that the spirits present a greater threat than the hobgoblins do, so she and Prang, the Iron Gauntlet leader, have agreed to an uneasy truce. Thus, the hobgoblins and the creatures of the Cairngorm Peaks are united in their struggle against Kalarel’s spirit army.
