• Brief Overview: Operation Decimation was the formal name given to the Tenth Sith Empire's post-Operation Hammerfall extermination and occupation campaign against Mandalore and the Mandalorian people. Following the Sith Empire's betrayal of the United Clans of Mandalore during and after Operation Hammerfall, as well as the subsequent Invasion by the Network. The Sith Emperor Darth Carnifex and Shadow Hand Darth Prazutis intended not merely to defeat Mandalore militarily, but to permanently cripple its population, erase its culture, strip it of beskar, and prevent the Mandalorians from reconstituting themselves as a unified galactic power.
  
  The campaign was carried out with terrifying speed by the Blackblade Guard and Sith Imperial occupation forces. Major clan centers were isolated, population zones classified, resistance leaders executed, beskar holdings confiscated, cultural practices suppressed, and surviving prisoners fed into forced-labor operations that stripped Mandalore's crust of beskar at catastrophic ecological cost. Speaking Mando'a was banned in occupied zones. Clan names and symbols were outlawed. Ancestral lands were seized and redistributed to Sith-Imperial settlers, collaborators, military administrators, and loyal industrial concerns. Mandalorian children and heirs were separated from elders in many regions, while armorers, historians, and cultural keepers were specially targeted for execution, forced service, or disappearance.
  
  The primary extermination phase became infamous as the Eight Weeks of Black Iron, during which Blackblade Guard units moved from settlement to settlement with machine-like coordination. It became the single deadliest genocide in modern galactic history. After organized resistance collapsed, the campaign entered the Beskar Reaping, a prolonged occupation and extraction phase in which prisoners were worked to death in mines and refineries while Mandalore itself suffered widespread ecological collapse.
  
  Though Mandalorians survived in diaspora, hidden enclaves, distant clans, and scattered resistance cells, Operation Decimation inflicted one of the most devastating wounds in modern Mandalorian history. It was not only an attempt to kill a people, but an attempt to erase their ability to remember themselves.

There are atrocities that end when the guns fall silent.

Operation Decimation did not.

It began in the aftermath of Operation Hammerfall, when the Tenth Sith Empire turned upon the United Clans of Mandalore after a period of alliance, cooperation, or strategic alignment. For much of its existence the Sith Empire maintained subtle, influential control over the Mandalorian state, following Darth Carnifex's puppeteering of Mand'alor the Undying Ra Vizsla, and a campaign of manipulation against Mand'alor the Hell Wolf Yasha Cadera. The betrayal was not a sudden battlefield excess, nor the uncontrolled vengeance of an enraged army. It was planned, administered, and executed as state policy, a reckoning long in the making after transgressions of the past. It wasn't until the Mandalorian State began to outlive its usefulness, that the Tenth Sith Empire finally struck. At its center stood Darth Carnifex, Sith Emperor of the Tenth Sith Empire and Darth Prazutis, Shadow Hand of the Sith Empire and one of the principal architects of its most devastating campaigns.

Prazutis understood Mandalore in a way many conquerors did not. The Mandalorians were not merely a military population. They were a civilization of memory, oath, armor, bloodline, adoption, language, and ancestral obligation. They had survived defeats before. They had survived occupation and utter disaster before. They had survived the loss of worlds, leaders, and fleets. To defeat them in battle was not enough. To occupy their world was not enough. To break Mandalore, the Sith would have to attack the deeper structure that allowed Mandalorians to endure beyond defeat.

Operation Decimation was designed around that principle.

It came in the aftermath of Operation Hammerfall, the sudden and overwhelming invasion of Mandalorian space that saw the world occupied by the Sith. Mandalorians found themselves herded on reservations, their rights limited. Both Carnifex and Prazutis had come to the conclusion that the complete and total eradication of the Mandalorian culture was the answer, long before the then Mandalorian Empire rose from the mists of obscurity, and forged designs to that end on a long-time scale. It wouldn't be until much later, when the Network's invasion of Mandalore, the last-ditch efforts at liberating the world failed that everything changed. The Zambranos had moved their timetable up significantly, to punish the Mandalorians who dared rise against their conquerors. Operation Decimation was comprehensive annihilation.

The campaign targeted the Mandalorian people across five intertwined fronts: Military annihilation, population control, cultural erasure, economic/resource seizure, and ecological denial. It was an extermination campaign, an occupation doctrine, and a resource-stripping operation fused into one administrative machine. In later histories, survivors would say that the genocide was decided in days, executed in weeks, and harvested for years.

Planetary Lockdown

Immediately after the Networks Invasion, Sith Imperial forces moved to secure Mandalore's orbital approaches. The first objective was not simply to prevent further attack and insurrection, but to prevent escape, coordination, and truth from moving faster than Sith command could control. Orbital interdiction screens were deployed. Civilian traffic was halted or redirected. Spaceports were seized. Clan-operated landing fields were bombed, stormed, or placed under lockdown. Communications relays were compromised. Distress calls were jammed, delayed, or manipulated. Sith intelligence units fed false commands into damaged Mandalorian networks, directing survivors toward compromised rally points or evacuation corridors that had already been marked for seizure.

For the first several days, Mandalore did not fully understand the shape of what had happened. Many believed the Sith were securing the planet after the Invasion. Others believed they were enforcing temporary martial control. Some clans attempted to negotiate. Some prepared to resist. Others moved to evacuate their noncombatants.

Prazutis had already anticipated all three responses. Blackblade Guard spearheads struck the major nodes first: Spaceports, communications towers, clan assembly sites, hospitals, armories, foundries, and administrative centers. Sith forces took particular care to seize or destroy locations where Mandalorian leadership could gather, broadcast, or organize. The campaign began by cutting the world into isolated pieces. A clan could fight. A people could resist. A planet divided into sealed districts, dead comms, broken roads, compromised evacuation sites, and falsified command signals could be processed.

That was the first horror of Decimation. It did not begin with firestorms. It began with silence.

The Census of Death

Once the major routes were sealed, the Sith Imperial occupation authorities began population classification. To outside observers, this stage looked bureaucratic. To those trapped within it, it was the moment death became organized. Entire communities were sorted by clan affiliation, combat capability, family lineage, professional value, cultural importance, and projected resistance risk. Sith administrators drew up classifications that determined whether a person would be executed, interrogated, displaced, enslaved, relocated, or assigned to forced labor. Prazutis' role in this stage was central. As both strategist and administrator, he oversaw the conversion of Mandalore from a defeated enemy world into a mapped system of targets, resources, and liabilities. Population centers became grids. Clan territories became files. Beskar vaults became inventory. Ancestral estates became seizure orders. Living people became categories.

The most dangerous categories were marked for immediate elimination.

Clan leaders, battlefield commanders, Protectors, veteran warriors, communications officers, resistance organizers, and rallying figures were prioritized. Mandalorian armorers and smiths were treated with particular severity, as they represented not only military value but cultural continuity. Historians, teachers, genealogists, religious or oath-keepers, and oral tradition bearers were also targeted in many regions. The Sith understood that Mandalorian culture didn't survive only through armies. It survived through those who remembered.

This stage gave Operation Decimation its lasting administrative infamy. The genocide didn't merely kill. It catalogued in preparation of what was to come.

The Eight Weeks of Black Iron

The primary extermination phase of Operation Decimation became known among survivors as the Eight Weeks of Black Iron. During this period, the Blackblade Guard became the most feared instrument of the campaign. Their advance was remembered not as a single battle, but as a sequence of synchronized annihilations. They moved through Mandalore's cities, keeps, mining settlements, clan halls, fortress-compounds, rural strongholds, and underground shelters with terrifying speed. Their method was deliberately impersonal.

The Blackblade Guard didn't descend upon settlements like raiders. They arrived like a machine. Perimeters were established. Escape paths were sealed. Communications were cut. It came region by region, settlement by settlement, district by district, street by street. Once a district was under complete lockdown, inhabitants were sorted, stripped, marked, and removed. Those targeted would find themselves stripped of everything, dehumanized and exterminated in predetermined killing grounds. Those who resisted would find themselves made example of. Those assigned for labor were transported toward mining zones, processing camps, or refineries. Those marked for intelligence were taken into detention networks and often vanished.

Almost overnight entire cities were emptied into little more than silent ghost towns devoid of life. Others were destroyed, transfigured into nothing but smokined ruins and charred bone of what once was. Some clans attempted to evacuate children, elders, armorers, or sacred relics, only to find evacuation corridors compromised. Others chose last stands around clan forges or ancestral halls. In several regions, Mandalorians attempted to destroy their own beskar vaults rather than allow the Sith to seize them; These sites became scenes of some of the most brutal close-quarters fighting of the campaign. Resistance was frighteningly brief.

The Blackblade Guard's reputation was forged deeper during these weeks. They were remembered as black-armored butchers who didn't shout, didn't bargain, and didn't slow. They were the visible edge of the Zambranos larger design: Mechanized, loyal, relentless, and efficient. Historians remember it as the only time the Blackblade Guard was deployed in its entirety, in its entire operational history.

By the end of the Eight Weeks of Black Iron, the Mandalorian population within Mandalorian space had been shattered, the amount of dead uncountable. No bodies remained of the horrific event, consumed in molecular furnaces, killing grounds dismantled. Surviving warriors retreated into hidden pockets, fled off-world if they could, disappeared into ruins, or joined scattered resistance networks. Many more were dead, imprisoned, or enslaved, and the killing continued.

The Beskar Reaping

After the primary extermination phase came the second great wound: the Beskar Reaping. Prazutis ordered the systematic confiscation of Mandalorian property, with special focus on beskar in all its forms. Clan vaults were opened by force. Ancestral armor was seized from the living and the dead. Foundry stockpiles were inventoried and transported off-world. Sacred weapons were taken. Family heirlooms were melted down, catalogued, or shipped to Sith facilities. Armor belonging to fallen warriors was stripped from bodies in battlefield reclamation zones.

To the Sith, beskar was a strategic resource. But its seizure was more than that. To Mandalorians, it was more than metal. It was inheritance. Identity. Family. Oath. Continuity. Prazutis understood this perfectly. That was why the seizure was so thorough. Beskar was taken not only to arm Sith war machines, but to humiliate and spiritually wound the people from whom it had been stolen. Armor passed through generations vanished into Sith vaults, Blackblade stores, imperial foundries, and trophy halls. Some lots were reforged into weapons, armor plating, ceremonial objects, or gifts to favored Sith commanders. Others were preserved as records of conquest.

Where possible, Mandalorian armorers were forced to assist in classification and smelting. Those who refused were executed, tortured, or replaced. Those who cooperated often did so under threat to surviving kin. The Sith sought not merely to seize beskar, but to corrupt the sacred process surrounding it. The Reaping soon expanded beyond existing holdings. Forced strip mining operations began across Mandalore. Surviving Mandalorians, prisoners of war, political detainees, dissidents, and other captive populations were assigned to mining and refining complexes. The goal was not sustainable extraction. It was rapid depletion and denial. The Sith sought to strip Mandalore's crust of as much usable beskar as possible before resistance, outside intervention, or logistical limits could interrupt the campaign.

The consequences were devastating.

Mining networks were expanded without regard for geological stability. Ancient tunnels collapsed. Aquifers were poisoned. Industrial runoff contaminated surrounding regions. Refinery zones became toxic wastelands. Surface scars widened into dead belts where neither settlement nor agriculture could survive. Sacred landscapes and ancestral territories were carved open for ore, slag, and transport corridors. Regions that had already survived bombardment were rendered uninhabitable by extraction.

Mandalore was consumed, and what remained had been renamed Moridinae.

Cultural Erasure

The genocide didn't limit itself to bodies, weapons, and mines. Operation Decimation also sought to destroy the structures by which Mandalorians remained Mandalorian.

To assist in the genocide, Lirka Ka was appointed as Grand Moff in charge of the Mandalorian sector. Together they drafted a series of Anti-Mandalorian Laws and Regulations. Teyn Gratiir who had become known as Mand'alor the Conciliator was installed as a puppet ruler. The speaking of Mando'a was banned in many occupied zones. Public use of the language could result in imprisonment, forced labor, punishment of family members, or execution depending on the district and period of occupation. Clan names and symbols were outlawed or restricted. Banners were seized and burned. Public rites were forbidden. Traditional gatherings were treated as sedition. Songs, genealogies, oath recitations, and oral histories were suppressed.

Schools and communal halls were repurposed for Sith-Imperial indoctrination, military administration, or settler governance. Surviving children in occupied territories were often separated from elders who could pass down clan memory. Some were forcibly relocated. Others were placed under imperial supervision, assigned new names, or raised in systems designed to sever their relationship to Mandalorian identity. Mandalorians were forbidden from owning weapons and armor of any kind, the ownership of Beskar in any form was especially taboo, unless directly sponsored by the Sith.

The Sith targeted armorers and cultural keepers with special intent. They were considered living infrastructure of resistance. An armorer could preserve technique. A teacher could preserve language. An elder could preserve lineage. A singer could preserve grief. A child could inherit all of it.

Prazutis' policy treated each of these as threats.

Cultural archives were seized. Some were destroyed. Others were transported to Sith repositories, where they became trophies, intelligence resources, or instruments of humiliation. Clan records were altered, erased, or weaponized. In some places, the Sith posted rewritten histories that framed Mandalorian resistance as criminal rebellion, clan identity as barbarism, and Sith rule as the necessary end of Mandalorian chaos.

The intention was clear. Mandalorians were not simply to be killed. They were to be made unable to continue themselves.

Resettlement and Imperial Colonization

As Mandalorian populations were killed, enslaved, deported, or driven into hiding, Sith authorities began redistributing ancestral lands. Clan territories, estates, agricultural holdings, mining rights, and settlement zones were seized under occupation decrees and reclassified as imperial property. Some lands were granted to Sith Imperial military governors and administrators. Others were opened to loyal settlers, industrial concerns, collaborators, and imperial families brought in to stabilize the occupation. In key regions, Mandalorian place names were replaced with Sith Imperial designations. Public monuments were torn down and replaced with symbols of imperial authority. Clan halls became barracks, command centers, warehouses, prisons, or administrative offices. Sacred sites were desecrated, fortified, or sealed.


The Sith sought to make Mandalore less recognizably Mandalorian with each passing month. The world itself was renamed Moridinae. Resettlement served several purposes: It rewarded loyalty, created occupation infrastructure, diluted surviving local identity, and established a population invested in continued Sith control. It also ensured that even if Mandalorians returned, they would not return to an empty world waiting for them. They would return to homes occupied by others, lands renamed by others, and graves paved beneath imperial roads.

For many survivors, this became one of the deepest wounds of Decimation. Death could be mourned. Theft could be avenged. But to see one's ancestral land filled with the flags, families, and offices of the conqueror was a slower cruelty. It turned return itself into conflict.

The Hollowing of Mandalore

The final stage of Decimation was not a single operation, but the cumulative result of occupation, forced labor, extraction, ecological devastation, and cultural assault. Mandalorian survivors later called it the Hollowing.

By this stage, the Mandalorian population had been catastrophically reduced. Its major centers had been broken. Its mines were unstable. Its industrial zones were poisoned. Its clan lands had been seized, depopulated, or destroyed. Its beskar reserves had been stripped, hidden, or removed. Its public culture had been driven underground. Its language was spoken in whispers, in exile, or in defiance.

The planet itself bore the wound.

Dust storms carried industrial ash across deadened regions. Rivers near extraction complexes ran dark with contamination. Collapsed mining zones swallowed old settlements. Fields failed where refining runoff had poisoned the soil. Wildlife fled or died in regions altered by heavy industry and bombardment. Entire areas were abandoned except for occupation patrols, slave labor convoys, scavengers, or resistance remnants. An entire hemisphere had become known as New Gratos and resettled with monstrous Graug who poisoned and ruined everything they touched.

Mandalore had endured war before. This was different. Operation Decimation made the land itself feel punished; violence bore into the bones of the world.

Legacy

Operation Decimation became infamous across the galaxy not merely because of the number killed, but because of the clarity of intent behind the atrocity. Over eighty five percent of the Mandalorian population had been exterminated. The Tenth Sith Empire attempted to dismantle an entire people with method, policy, and industrial force. It placed bounties on Mandalorians and information that located distant refuges. For the Sith and later Kainate-aligned historians, Decimation became an example of what Prazutis and Carnifex's doctrine could accomplish when unleashed without restraint. It demonstrated that a warrior culture could be broken not only through battle, but through logistics, language suppression, forced labor, resource seizure, resettlement, and memory warfare. To Sith strategists, it became a case study in total civilizational dismantlement.

For Mandalorians, the memory was different.

It was remembered in fragments: The silence after the comms died, the black armor at the gates, the burning clan banners, the forbidden language, the stolen helmets, the mines, the poisoned rivers, the ancestral halls filled with foreign settlers, the children told not to speak their own names, and the knowledge that the enemy had not merely wanted them dead. The enemy had wanted them forgotten.

Operation Decimation failed in that final ambition.

The Mandalorians remembered, and because they remembered, the genocide became more than a wound. It became an oath. Never again.
