Xenocide (1991) is the third novel in the Ender's Game series of books by Orson Scott Card. It was nominated for both the Hugo and Locus Awards for Best Novel in 1992. The title is a combination of 'xeno-', meaning alien, and '-cide', referring to the act of killing; altogether referring to the act of selectively killing populations of aliens, a play on genocide.
On Lusitania, Ender finds a world where humans and pequeninos and the Hive Queen could all live together; where three very different intelligent species could find common ground at last. Or so he thought.
Lusitania also harbors the descolada, a virus that kills all humans it infects, but which the pequininos require in order to become adults. The Starways Congress so fears the effects of the descolada, should it escape from Lusitania, that they have ordered the destruction of the entire planet, and all who live there. With The Fleet on its way, a second xenocide seems inevitable.
Following the events of Speaker for the Dead, a group of characters are depicted living as members of a Brazilian Catholic human colony on Lusitania, a unique planet inhabited by the only other two known species of sentient alien life: the Pequeninos "little ones" and the Hive Queen. The pequeninos are native to the planet, while the Hive Queen was transplanted to this world by Ender, partly in penance for his near-total destruction of her Formic species in Ender's Game.
Echoes,
drifting through Space.
Free from the malice,
distortion, and everything that is organized thought!
Vast!
Dark energy reigns.
Weaponized and used!
Destruction envelopes as Extinction follows
Existance.
Bound to a strange dimension.
Subservience or termination!
Negligent resistance from those who oppose.
Our kind, one mind!
We pursue the Ultimate Truth!
All sentient worlds are commodious,
necessary tools for Galactic Control!
As Our grip grows tighter,
devolution takes place and more systems fall!
Through brutal oppression,
conditioned by Eternal War!
The time for harvest nears,
and life shall bear no weight!
The search for equilibrium
shall balance this great plain.
We will take control
and depredate your Mother Star!
One last glimpse of light,
before Everlasting Dark!
Ruled!
By an unseen force.
Bred!
For Galactic Control.
Killed!
In order to serve.
We are the Deadfall,
octal and machine.
We are Legion,
inheritors of this Galaxy!
Keeper of the Fire
Prime Architect!
Destiny of Quadrality
Universal subsistence!
How can you fathom what lays beyond?
Existance in eleven dimensions is an absurdity
to beings that resonate in four dimensional Reality!
The colors and spectra.
Incomprehensible shock and awe!
You cry out in agony as our
mothership descends to cull!
Weak and pathetic!
You tremble and ask us why
We look down and all eight eyes
vaporize what's left.
Our intent: Harvest souls for Mass Ascension.
