Players will be thrust into the dark, war-torn world of Cairn where a once proud empire has been brought to ruin and the human race driven to the edge of extinction. Cairn has become ground zero of an eternal war between two otherworldly powers, one seeking to use human bodies as a resource, the other intent upon destroying the human race before that can happen. This cataclysmic war has not only decimated human civilization but is warping the very fabric of reality and, in its wake, giving life to new horrors.

For humankind it is the dawn of a grim new age where iron has replaced gold as currency and the importance of salt as a weapon makes it far too valuable to waste on food. Small enclaves of human survivors exist scattered throughout the world, holed up in hidden refuges. These humans have quietly watched the warring invaders destroy one another and have become wise to the strengths and vulnerabilities of their otherworldly foes. A few survivors have begun to exhibit strange new abilities after surviving possession or exposure to the warp. These unnatural powers are feared by some but give many new hope of launching a resistance to fight the "outsiders" and reclaim what's left of their world.

Crate Entertainment announced that Grim Dawn's 2nd expansion, Forgotten Gods, is scheduled for March 27, 2019.

In the Forgotten Gods expansion, you will journey beyond the bounds of the Erulan Empire, traversing burning sands, lush oases and volcanic wastes to reach the sun beaten ruins of a city with secrets that should never have been disturbed. The flames of a forgotten god have been rekindled, sending ripples through the Eldritch realm and sowing terror even among the Witch Gods themselves.

Featuring a thrilling new chapter in Grim Dawn’s story, a new gameplay mode, quality of life features, hundreds of new unique items and more, the Forgotten Gods expansion will be an exciting densely-packed new addition, whether you are a dedicated player or just starting out with Grim Dawn.

Where once stood mighty cities and temples, nature has reclaimed. The molten fires of a vengeful god’s fury have long since cooled, giving rise to the Basalt Crags. But tread carefully, for the land itself still weeps in agony of a forgotten tragedy. What remains now of the City of Abyd are ruins and fire, magma and embers.

And the valley beyond…once a sacred place lined with tombs and temples…consumed by flames. But it there that you must go if you are to learn the truth and vanquish the terror that threatens to drown the world in its torment.

Will you survive the inferno? Or be devoured by its rage?
