More recently a third kind of Power has been created, referred to as a Neutral Power. In effect, this is a Power which, either by accident or design, has elements of both the Constraining of Chaos and the Imposition of Order. Neutral Powers do not take completely opposite relationships with either Pattern or Logrus. However, by quirk of fate, they do all become polar opposites of other neutrals.
The first Neutral to be made was the Twister, created by Kelric. All stories indicate that he was attempting to draw a Pattern, but he was disturbed during the process by an attack of Abyss Hags, and the Creation went wrong.
The second Neutral was created by Corwin – while again attempting to Create a Pattern, it is clear that he either had not studied sufficiently, or attempted to change too many things as he went, such that he also ended up creating something that is not a Pattern.
