Negative Corridor is a one-shot chapter, possibly taking place in the Blame! universe. It is included as a bonus chapter in most editions of NOiSE.
Synopsis[]
Somewhere in the City, there is an order of cyborgs (possibly Silicon creatures). One of them retrieves an archived container with a sample of a moth’s wing.
Inspired by the moth’s form and life cycle, she undertakes to change herself. She forms a chrysalis, which grows in size and remakes her body into an adult form with moth-like features. Others are inspired to join her.
The changed cyborgs ascend to a precipice and fly away.
