The Mists of Paoru
Magic and Yokai
Certain schools of magic correspond to different aspects of the yokai world known as the mirror world. The mirror world can be represented along a spectrum of energy from Positive or Spirit to Negative or Void with the 5 elements arranged between.
Necromancy and it’s relevant spell like effects correspond to the Void or Negative Energy part of the Yokai Spectrum. Magic users who use necromancy begin to become tainted with Void energy which can colour their experiences with other magic users and zhurdana as their skill has its basis in Spirit energy. Necromancers often find themselves being hurt by the Zhurdana’s skill.
Divination and it’s relevant spell like effects correspond to the Spirit or Positive Energy part of the Yokai spectrum. As those who practice necromancy are marked by Void energy, those who practice divination spells begin to become marked by Spirit energy. As this energy builds up, they often find that Zhurdana skills work twice as well on them with the Zhurdana only taking half the damage they heal.
