It had been many years since the fall of the Empire and the Rise of the New Republic, and even more since the end of the Republic's war against the Separatists. Most had forgotten about the droid armies as the clones had destroyed their factories and smashed what few units remained. It had been such a successful campaign, most in the galaxy had forgotten the very existence of the mechanical soldiers.

Constructor Zolvan had been waiting for such a moment in time. Standing on the bridge of the droid control ship as it broke through the clouds and descended on the unsuspecting world of Kajeer, Zolvan watched the holomaps closely. Golden yellow, his mechanical eyes observed the transparent blue representations of his forces. Hovering tanks began unloading as the massive vessel settled to the ground while droid fighters raced out of the open hangar decks to fill the skies like swarms of mechanical insects. Similar to the factories he'd been built to oversee on Geonosis, the invasion was moving forward with the absolute precision he demanded.

The people of Kajeer had been broken years ago when the Empire set up factories for the production of war material. Every citizen, no matter their qualifications or age, had been pressed into service, and every industry not of immediate use to the Empire was abandoned. Agriculture ceased as mining facilities and massive factories covered the surface of the planet with production lines and toxic byproducts. Grasslands, once fertile and rich, became covered in poisonous sludge, and even the air itself was darkened by thick clouds of billowing fumes from the factories. Respirator masks were required outside the facilities, but the workers rarely left as living quarters the equivalent of prison cells had been provided within. The lives of the people of Kajeer had been of constant labor, hardship, and no hope for improvement of their situation.

When the Empire fell, those in command of Kajeer took what supplies and people they wished, and evacuated off world to regroup with the remnants of the Imperial Fleet under Grand Admiral Thrawn. With their entire infrastructure supported by the Empire's imports, the people of Kajeer were left with a poisoned world and no food or medicine except what had been left behind by the fleeing Imperials. The weapons they'd made were quickly turned against each other as the people tore apart what was left of their civilization, fighting over scraps to live another day.

Constructor Zolvan had seen similar patterns unfold before all across the galaxy, and his programming compelled him into action. The droid armies were quick to smash aside what little resistance was offered. There were no coordinated defenses or organized military forces to impede the near immediate takeover of the entire planet. Citizens had been used to the iron hand of the Empire, so Zolvan knew they would quickly adapt to his mechanical grip, but unlike the fear instilled by Imperial agents, Zolvan had other tactics to employ.

Behind the tanks, under the guard of hundreds of battledroids, hovering cargo haulers slowly moved into the cities. A square platform piled high with armored crates and covered over by a protective tarp, the haulers moved into position and powered down, stubby legs folding out underneath to take the weight as the repulsorlift switched off.

The tanks took up covering positions while battle droids began unloading the crates. Zolvan oversaw the operation from the bridge, watching each numbered cube of supplies on the projected hologram move out and to the designated delivery point. His droids performed their task flawlessly, doing their task with the efficiency an organic worker would've taken years to master and coordinate. Although pleased with his efforts, Zolvan didn't allow the emotion to disrupt the order of his thoughts. Food and medical supplies were delivered distribution areas where his droids would parcel out designated amounts to the population in return for their continued service in the production of war material.

While his droids were tending to the workers, other forces had already secured the factories, assessing the damage caused by infighting or sabotage, and estimating the requirements for repairs and necessary upgrades to eliminate pollution.

Zolvan knew more than most about large scale industrial production, and the Empire had clearly not been concerned with the damage they were doing to the planet or its people. The levels of pollution and lack of safety measures would've caused a catastrophic failure in due time if the Empire hadn't withdrawn. Waste was a hateful thing to Zolvan; it was wired into his very circuits. Workers were as much a valuable resource as the planet itself, and things that threatened either were unacceptable impedances to his intended goals. Organic workers could be superior to droids, the Clone Wars had proved as much on the battlefield, so Zolvan intended to see to their care as much as to the factories he commanded.

Programmed to build an army capable of conquering the galaxy, Zolvan had been moved off Geonosis to reorganize a satellite facility just prior to the battle with the Jedi. Command had ceased to give orders, so Zolvan took one of the last droid control ships in orbit and departed for deep space. Many of the crew had objected, but his authority over the robotic military onboard quickly put an end to any thoughts of insurrection. In order to carry out his programming, Zolvan had dispatched countless probes to observe the galaxy and ascertain how many droids would be necessary to conquer everything.

Data analysis of the nearly continuous warfare across countless star systems began to form a pattern and an inescapable conclusion in Zolvan's robotic mind. Planets were being destroyed or worked to exhaustion. Space fleets were smashed to debris, and ground forces were slaughtered in great hosts. Civilizations were broken, and what little was built up after years of effort was quickly destroyed when the next war broke out. Zolvan realized he wouldn't need to conquer the galaxy in a head-on attack as other armies had tried to do. He needed only to wait until the various factions blasted each other to nothing but shattered remnants, then he could march forward and collect the pieces, putting them to a more productive purpose.

Year after year, the wars raged among the stars while Zolvan quietly gathered supplies and worked unseen. Worlds broken by the wars, like Kajeer, were absorbed. When the galaxy finally took notice of his efforts, it would be too late for their ragged armies to put together any kind of defense to counter the mechanical forces he'd been creating without pause. The defeated worlds would welcome his forces as liberators from constant war and strife, or they would be dealt with by his armies. Either way, it didn't matter, for Zolvan would complete his programmed mission and take the galaxy.
