Eternity

Eternity is an ethereal realm where the spirits of all Ankouvian creatures go when they die, regardless of species, morality, or any other qualifications. All creatures are equal in Eternity. It appears as an endless sky dotted with stars. While there is no ground plane in Eternity, there are clouds drifting along that can be stood upon if a creature so desires. All creatures have the ability of flight in this realm, regardless of whether they did in life.

When creatures arrive in Eternity, they carry little memories of their past lives, only a deep sense of peacefulness and contentment. If a pair or a group of creatures had a strong bond during their time alive, whether romantic or platonic, they may find each other in Eternity; although they will have no specific memories, they will feel something familiar about the other, and will understand that they belong together. Thus "I'll find you in Eternity" is a common way of expressing one's deep love among Ankouvian creatures.

The Gryphon Mother spends a day in Eternity every time she reincarnates, but she retains her memories. She uses this time to reflect on the life she has just left, and to prepare for the one she is about to enter. The Beast also spends a day in Eternity between reincarnations, but she does not retain awareness or her memories, and instead experiences a peaceful fuzziness like any other mortal creature, until eventually she falls back into her now-healed physical body back on Ankou.

Spirits can move freely in-between Ankou and Eternity. They also retain their memories when in this plane. As spirits cannot die naturally, they travel to Eternity themselves when they tire of life on Ankou. The longer they stay in Eternity, the more their memories start to fade, until eventually they find themselves as blissful and peaceful as any other creature who had died naturally.

If a creature had strong ties to a specific location on the planet, it is possible for their spirit to wander back down to that place, where they appear as a ghostly, disembodied version of themself known as a Soul. They still retain the usual distant fuzziness of Eternity, and are not fully returned to consciousness, but in rare cases they may have small moments of lucidity.
