Shadows: Heretic Kingdoms - Shadow Realm

Games Farm's posted a new update for Shadows: Heretic Kingdoms that talks about the Shadow Realm. So here is the information taken from the website.

The Shadow Realm

The space between dimensions has long been referred to by mages as ‘the Dreamworld’, since in this dimensional hinterland the dreams of the living and the souls of the dead bleed into mortal existence, bringing nightmares to those sensitive to these disturbances. Long before the death of the God of the Land and the shattering of the Godslayer sword, the Dreamworld was an ethereal place, connecting an endless number of dimensions into what the Taymurians call the Tree of Worlds. But when the Godslayer Sword was shattered, the dimensions shifted and the Dreamworld of the Heretic Kingdoms was severed from all dimensions except for the hellish Shattered Heaven.

Legions of demonic creatures from Shattered Heaven have now invaded the Dreamworld and shifted this dimension into darkness. Whereas before mages and other supernatural beings could shift between the Dreamworld and the mortal realms freely and safely, now all that remains is a dark fragment of what this dimension once was. Sages no longer dare call this a world of dreams: they call it Shadows. This shift in the dimensions has also made it far easier for demons to enter the realms of mortal souls. Whereas before, a mage would have to invoke a hell gate to summon a demon, now many demonic entities are being inexorably drawn into Shadows by the essence of the living souls that seeps out through death.
