Shades and All other Beings of that realm

SHADES
Shades Lack any and all physical existence. They are beings damned to eternal damnation where they will constantly be torture; have a voice, but can not use it, have a mouth but can not eat. Shades, How ever pathetic their existence is are a serious force to be reckoned with. Since they lack all physical and Auratical essence They can not be damaged by Physical or Magikal attacks, Shades Devour whole essences in packs By slowly corrupting one's essence with a Remittance of an ancient Great Beast Known as Khaos. the resulting effect of Being killed by a shade is that you become a shade. Although Shades are mainly in their own realm known as the Shade Realm. The only way For a shade to leave their realm is if someone were to either 1.) summon them. Or 2.) Rip a hole/portal/tunnel through the realms. To kill a shade one must be a shade, nearly literally, If physical and magikal can not damage them, what about themselves? Shades can kill each other.
