Trope-a-Day: The Ark

The Ark: One of the projects of the Emergency Management Authority/Fifth Directorate are the “Civilization-Backup Ships”, ark vessels hidden in deep space with as close to a complete backup of civilization as can be managed – the notion being that in the event of an extant existential threat large enough to threaten the survival of civilization entire (what’s called in the jargon a hard civilization kill event), they’ll come online under CASE NIGHTFALL ASUNDER, get the hell out of Dodge, and reboot it somewhere else.
