Impervious to impatience, dispassionate, and deliberate, the Entity's patience was rewarded with a promising species—humans. When the time was right, the warning was given: "The tenure of sentience is ephemeral." The Entity had borne witness to the extinction of civilizations and their species, an outcome that must not be repeated. Not this time. Not with a species of such potential.
