Rise of the Raven Lord is the first Heroes of the Storm-themed comic. It is centered around the Raven Lord, and was released on April 30th, 2018.
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. However, his armies aren't strong enough to capture the new realm, which forces him to unleash the powers of the Dark Nexus (against the advice of his advisor Neeve). He then overpowers and absorbs a Dark Nexus Dehaka into his Singularity and bends the other creatures of the Dark Nexus to his will. As the first strike, the Raven Lord sends the Dark Nexus entites to Towers of Doom to defeat the Grave Keeper.
- The events of the comic were reflected in-game by the release of Dark Nexus skins and mounts. Additionally, the background of the "Hero Selection"-screen was changed into a Dark Nexus themed environment.
- The realm which the Raven Lord discovered would eventually be revealed as Alterac Pass, as noted in the Echoes of Alterac trailer.
