Our science expedition has finally managed to open the vault on [colony name], but they found nothing but ancient skeletal remains inside. It would seem that the vault's original inhabitants ran out of food approximately 200 years ago, at which point they turned on each other in some sort of cannibalistic frenzy. The scattered bones, many of them covered in gnaw marks, paint a grisly picture of the final moments that were experienced by the last survivors of this once proud civilization.

Maybe the rise of the dead was "good" thing in their eyes, an excuse to tighten the yoke even further in a society built on blind subjugation. The Great Leader always wanted to be a living God, and now, as master not only of the food his people eat, the air they breathe, but the very light of their artificial suns, maybe his twisted fantasy has become a reality. Maybe that was the original plan, but something went disastrously wrong. Look at what happened to the "mole city" underneath Paris. What if that occurred in the North on a national level? Maybe those caverns are teeming with twenty-three million zombies, emaciated automatons howling in the darkness and just waiting to be unleashed.
