Under The Sun
Kalarel is behind the plague of undead that have besieged Nentir Vale. He is gathering necrotic weapons and imprisoning souls, but for what ultimate goal?
He and his cultists have taken base at the Keep on the Shadowfell.
Kalarel is formerly Karl, an orphan of Winterhaven. Exiled years ago for various mischief, Kalarel feels both pity and hatred towards the commonfolk of Winterhaven.
