Plane of Shadow -- does anyone use it?

[Baron Opal]

I merged the plane of shadow with Acheron in my cosmology. The remenants of the golden age still wage war on a vast, broken plane that strangely mirrors our own. Seven cities of golden archetecture dot the landscape, providing easy access to certain planes. What makes the plane of shadow so appealing is that it allows people to plane travel by simply walking there, if you know where the doors are.

The ethereal is also present, as the Ethereal Sea, and so it is a kind of ethereal and astral merged into one. It is the "lowest energy" plane so it has connections everywhere. Even places that can't be reached by shadow can be reached by the ethereal. But, there are no real landmarks in the ethereal and you need either a strong will or a githyanki ship.

In my D&D experience so far, I just haven't seen the Plane of Shadow used very often -- when it has been used, it's just a few random encounters due to a shadow walk spell or similar.

Does anyone use the Plane of Shadow extensively in their games? What stuff did you focus on?

Extensively? Yup!

IMC, every shadow you see is an extension of the Plane of Shadows. The Plane of Shadows is the transitive plane that links the Middle World to the Hells. There are no shadows (resulting in everything softly glowing) in the Heavens.

This has major effects, including more shadow creatures and more people who use the Plane of Shadows for malefic magic (special feats modified from Forgotten Realms).
