Shadow

The shadow energy (aka Shadow Plane) is not limited to a single plane; it is instead an integral part of every aspect of the universe, woven into every plane. Thus, spells that call upon this energy, such as shadow conjuration, draw upon local sources rather than reaching to another plane. Positive energy remains associated with the energies possessed by living beings, and negative energy with the motive forces of death and the undead. Magical weapons that have effects wielding this energy draw upon energy bound into their own material, freed by enchantment. "Shadow" is spell type common to many items and spells created by the Shadow Council and other such nefarious organizations. The arcane and shadow magic appear to be tied together. Shadow appears to be split into subcategories or is synonymous with "Darkness", "Negative", "Death", "Destruction", "Chaotic", "Evil", and "Fel".
