Deathly Plane of Shadow

The plane of death and shadow is itself chaotic neutral in alignment, but its inhabitants tend strongly towards evil. Which is to say, death and darkness are neutral things, but those who love it are overwhelmingly evil.

The natives of the Plane of Shadow include shadow creatures, some undead, and the drow. It is known that it is easier to construct infinite lines on the Plane of Shadow than it is to construct finite lines, which is why this plane is second only to the astral plane in usefulness for travel.
