The Raven Lord thinks other Realm Lords are "grasping and weak," and have no clue as a distant invading force is heading toward the Nexus, intent on destroying it. The Raven Lord has discovered a new Realm, and believes conquering it will help him repel the invaders.

While Deckard Cain wanders around the forests of Dragon Shire, he is attacked by some knights who are looking for a girl called Orphea. Orphea joins the clash and helps Cain defeating the knights. Deckard Cain and Orphea team up to find a solution for the Dark Nexus threat raised by the Raven Lord. They come to Raena the Lady of Thorns and Realm Lord of Dragon Shire, for help and warn her about the danger coming.

Orphea is the fourth Heroes of the Storm-themed comic. It is centered around the Orphea.
