A Guide to the Ethereal Plane is an accessory for the Planescape® setting using the 2nd-edition AD&D rules.
On the Great Ring, six planes lie in direct opposition. Above looms the triad of Good, holding fast against the tide of corruption. Below lurks the triad of Evil, stained red by the eternal Blood War. Both resist the pull of Law and Chaos. Any berk who calls them "neutral" planes has never experienced their full extremes!
