Abyss is a plane of existence in Owlcat Pathfinder Games.

Description (Kingmaker)

“

The Abyss is a plane in the Outer Sphere dedicated to the rule of evil unfettered by law. It is accessible through huge rents in the Maelstrom, opening into fiendish depths, vast beyond imagining. The Abyss is possessed of many layers, strung together by the River Styx. Its inhabitants are demons, its rulers demon lords, who wrested control of the plane eons ago from the primordial qlippoth.

Description (Wrath of the Righteous)

“

The Abyss is a realm of infinite horror and unlimited danger. Its vast chasms, known as the Outer Rifts, wind throughout the surface of the Outer Sphere. Where the Outer Rifts of the Abyss open onto realms like Elysium or even Heaven, they are the sites of eternal wars against the celestial races. Here, the armies of good maintain permanent encampments along the edges of Abyssal rifts and do their best to prevent the rifts' spread. For spreading is the correct word. The Outer Rifts are growing, albeit slowly. Scholars believe that this is a sure sign of the end of all things, that nothing can stop the growing dissolution of the Outer Sphere, and that at some time in the future, the Abyss will consume it all. Worse, the Outer Rifts do not constrain themselves to the Outer Sphere — they can open elsewhere, and have done so countless times before to consume entire worlds. The malevolent Worldwound in northern Avistan is but the latest to appear in the Material Plane — a rent in reality that even the full might of the nation of Mendev is unlikely to contain for long. The Abyss is possessed of many layers strung together by the River Styx. Its inhabitants are demons, its rulers demon lords, who wrested control of the plane eons ago from the primordial qlippoth.
