Extinguishing is the process of being torn apart at a molecular level by Dusk. It is the result of a spike in the Dusk's evolutionary chain. When a Dusk is supplied with enough power, they can Extinguish people with a single touch. If within several hours, the source of the Dusk's power is depleted, the victim can be Reconstructed.
