SYNOPSIS & BACKSTORY
This story tells the untold backstory of how Caroline became GLaDOS and why she chose to eliminate the personnel of Aperture Science. It uncovers the origin of the Morality Core in the Portal universe, tracing the struggles of the scientists who survived the first neurotoxin leak to install it.
Spoiler alert: Almost everyone survived the first attempt, because the initial leak was never intended as the final purge. Discover the slow closing of exits, the illusion of corporate consent, and how Doug Rattmann navigated the backstage blind spots to survive the devastating second wave.
