The devastation was complete. No human could have possibly survived the attack from beyond the stars. The Aliens had come, in their massive dreadnoughts and battleships, destroying entire cities with their lethal plasma beams and fusion bombs. They poisoned both air and sea, destroying the fragile environment of the Earth in less than a week. Coastal cities were flooded out, the ruined buildings lying under countless tonnes of corrosive seawater. Those structures fortunate enough to be on higher ground were reduced to smoking concrete and molten steel slag. The skies were red with fire, often glowing an unhealthy green from the massive radiation levels.

The terrible Aliens had killed an entire planet, then simply left for the great unknown. Nothing could possibly survive on the charred and irradiated world, let alone thrive. The Earth was dead, fit only to be blasted into meteors. Soon, the Irken Armada would be here, but not even the terraforming crews could resurrect this broken, dead planet. The only use of this planet would be target practice for the Massive's supralaser cannon.

Another failed experiment in the cosmic game of life and death. Another speck of light snuffed out for all eternity, and perhaps longer still. From the wreckage of the human world, a single purple ship blasted off to meet with the Irken Armada. Inside the ancient Voot Cruiser, Zim couldn't understand why the Nanex Imperiuum had concentrated their entire naval force upon the doomed humans. What had the humans done to incur the wrath of the deadly Imperiuum? The Irkens, at least, used worlds for their purposes, often ripping out entire ecological systems in favor of cybernetic landscapes. The Nanex, though, simply destroyed and left worlds and star systems for dead. Zim only hoped that they would never come to blows with the Irken Empire and its formidable spaceborne navy.

From what the tiny Invader and his deranged SIR Unit had seen, the Irkens would follow in the ashes of the humans. Countless threads had been cut by the hand of Fate, with no rhyme or reason to their loss. Zim thought of the irony. Nobody had ever listened to Dib about his crusade, and they had paid for it with their entire race. The Irken spoke only one word, the emotion thrown into the single quote he would make for six months...
