Instant of Eternal
Trauma stems from two aspects of the Celestial’s connection with the vessel. The Celestial shares the memories and experiences of the vessel’s previous occupant, and that includes humanity’s innate fear of death. This makes the experience of death intrinsically traumatic. Second is the nature of the connection between the vessel and the Celestial. Because, to some degree, they have become an interwoven whole, the sudden separation that occurs when a vessel is destroyed creates a great deal of confusion and trauma in the Celestial.
It is also possible in such situations that the Celestial will lose the memories of what occurred while it was inhabiting the vessel after the traumatic death.
The reason that Malakim are not affected by trauma is their inherent purity. They cannot integrate with the memories and experiences of the vessel’s previous life. As such, they are neither affected by humanity’s innate fear of death, or the sudden shock of separation that occurs when a vessel is destroyed. (As such, however, Malakim are always considered “inhuman.”)
