Imperial Radch Wiki

The Four Emanations are an important concept in Radch religion, the components from which Amaat created the universe. Each Emanation is a duality between two opposing concepts.

The Emanations are:

  • EtrepaBo - Light/Darkness
  • EskVar - Beginning/Ending
  • IssaInu - Movement/Stillness
  • VahnItr - Existence/Nonexistence

Representations of the Emanations are often depicted in Temples to Amaat, or being held by a four-armed Amaat idol. They can also be depicted separately, and Breq keeps an EskVar with her other religious idols.

Decade naming[]

Radchaai military ships have a number of their decades named after the emanations. The first two decades are always named after the ship's god and Amaat, while each remaining decade is named after a half of one of the emanations.
