Shades

Shades are dead souls brought back to the world either by very powerful necromancers or by Jousus himself, and are bound to whoever summoned them. They look as they did in life, though darker, as if black pigment was mixed into their skin and clothes. The most telling cue is their eyes, which are black where they should be white.

They return to the world of the living with all the skills and knowledge they had in life, as well as with newfound sorcery.

They are not truly ethereal, but can remove their physical presence to the ethereal realm at will, and while still visible, are invulnerable to physical attacks, which simply pass through them. A young shade may not be able to fully go incorporeal, and may be somewhat affected these attacks.

Shades can be forced to remain fully in the physical realm if they are dusted with salt.
