In the Wildwood Forest, the Awoken leave no soul unattended. These plant-like creatures feed upon the souls trapped in their vines to nourish the Forest itself, slowly erasing the mind they’ve trapped in the process. As these souls lose their identity, they are reawakened as part of the Forest itself, forever growing its population of Animus and Hollows. And at the center of it all, the Sentient now guides these legions to fight with Hell and return to the Wildwood.

Deep within the volcanic wasteland of the Scorched Plains dwell the Hellhorned, the mighty warriors of Hell.

As the leader of both, Rector Flicker has united them under Hell’s banner to reclaim what they’ve lost.

Now, with Tethys Titansbane commanding their forces of Sirens and Mages, the Stygian Guard harnesses the power of their ancient prisoner to enact their revenge.

At the beginning of Hell, there was only a darkness: the Umbra. Over time, the Shroud spread throughout the Crucible, splitting into Antumbra Morsels to mine the precious resources within. Now ousted from its ancient birthplace, Penumbra, said to be the origin of the Shroud itself, has rallied the entire Umbra shadow to Hell’s cause against Seraph and the Winged.
