YAEYOEFUI: My people, and the galactic archeologists of our time, found enough relics of ancient civilizations to piece together a long, unpleasant history with a frightening pattern.
Sapience spreads at epochal intervals, breathing life into the galaxy every few million years.
Extinction of sapience blows closely behind it.
SORLIE: Extinction... What kind of percentages?
YAEYOEFUI: A hundred? That's what we assumed anyway.
But only because we never found survivors. Maybe you'll find something we missed!
SORLIE: Still a downer.
