The Fall of Oriath (released August 5, 2017) introduces a massive storyline extension with Act Five situated in the exiles' homeland of Oriath, and Acts 6-10 which revisits the areas of the previous five acts.The Exiles return to Oriath to liberate it from the tyrannical rule of High Templar Avarius, but things take a dark, unexpected turn when the dark god Kitava, freshly reawakened by the death of the Beast, hatches a sinister scheme to consume the souls of all mortal life.
Meanwhile, the original gods of Wraeclast are awoken by the death of the Beast and plot to take their vengeance on the mortals who had forgotten them. This streamlines the experience and level progression into a single play-through, incorporating the Cruel and Merciless difficulty levels in the process (Cruel begins after Act 5, Merciless after Act 10). In addition, a new Pantheon system is available that confers swappable passive bonuses for hunting down Wraeclast's enemies and gods.
A new entity called The Elder fights for control over the Shaper's realm, infecting the Atlas with his influence.
