1d6 Random Border Realm Creatures Encounter Table For Your Old School Campaigns

Working their way between the borders of dream and death in the Beyond are creatures that partially demon and made up from the souls of those who have passed far into the furthest reaches of  Pale. These horrors ply the border realms searching for victims and others they can violate, enslave, and trade to far darker powers for the chance to perhaps once again be human or regain the comfort of something resembling humanity. Such fates are often denied to these thrice damned and demented foils for far more dangerous powers. Many times these horrors are seventh level or better wizards who are sporting extreme mutations or alterations picked up in the border realms. 

The border realms serve as short cuts and jump points across the myriad of heavens, Hells, and portals across the Outer Darkness to reach worlds that are a part of the ancient and decaying interstellar empires of humanity. Many of these examples of sub humanity and abhuman corruption have made allegiance with the powers of Chaos and Horror long ago.
