Peace in the Republic has always been hard won, short lived and tenuous. A short two decades after the conclusion of the Great Sith War in 3,996 BBY, the Republic was once again thrown into war, this time against a new enemy. Across the galaxy the Mandalorian cults, united for the first time in centuries by the blood-thirsty Mandalore the Ultimate, began a campaign of hostility and genocide, pushing their way from the outer rim to Republic space. By the time this army of Mandalorian Neo-Crusaders had reached Taris, the Republic Senate was left with no choice but to commit themselves to pushing back the menace.

The Jedi Order, though, was hesitant to involve themselves. Wary of becoming embroiled in another conflict so soon after their Pyrrhic victory against Exar Kun, the Order distanced themselves from the conflict with the Mandalorians, refusing to commit Jedi soldiers to the effort. This created a schism in the Order, dividing those who wanted avoidance from those who felt the need to intercede in the conflict. Those who wanted to lend aid to the Republic in the fight were led by a charismatic young Jedi Knight named Revan, who began auguring for a more proactive role in driving out the invading army. Under Revan a splinter faction of Jedi, called the 'Revanchist', chose to defy the Order's wishes and assist the Republic's armies in the war against the Mandalorian Neo-Crusaders.

But the Jedi Order maintained their stance, refusing to sanction the actions of the Revanchist, and so Revan devised a plan to force their recognition of his involvement in the war. He took command a loose organization of volunteers to the Republic military dubbed the Republic Mercy Corps. This organization - comprised of doctors, engineers, scouts, and other non-combat specialists - were primarily focused on aiding the victims of war, and had long been friendly with the Jedi Order. To this end, the Order has never refused to allow a Jedi to serve with the Corps. By 'drafting' the Revanchist into the banner of the Republic Mercy Corps, Revan was able to force the Order to sanction his actions in the Mandalorian Wars.

Under Revan's leadership, the Republic Mercy Corps flourished. Their ranks swelled to four times their previous numbers, bolstered now by an influx of Jedi Knights and seasoned Republic combat soldiers. No one who wanted to serve was turned away, and every hand was put to its best use. During this time, the R.M.C. first began to see the specialization that would come to define the Corps in later year, as soldiers, medics, engineers and intelligence officers formed their own sub-factions within the R.M.C. With the unyielding force of the Corps behind him, Revan was able to begin driving the Mandalorians back. With each successive victory, the Republic began regaining lost ground. The Mandalorian Neo Crusaders were pushed off Taris and out of Republic space, and found themselves eventually forced to a final confrontation with Revan and the Republic army over the surface of the planet Malachor V. With Mandalore the Ultimate himself present at the battle, this was to be Revan's final blow against the Mandalorian aggression.

The soldiers and Jedi of the Republic Mercy Corps were brought in full force to Malachor V, where they were tasked with providing support for Revan's final push for victory. A Jedi Knight contingent, made up of Revanchists loyal first and only to Revan, joined their commander in his boarding of the Mandalorian flagship over the planet. Lead by General Pegarus Mourne, these Jedi soldiers cleared the flagship, allowing Revan unrestricted access to the Mandalorian leader. The Corps' common soldiers and support troops, under the leadership of General Jonah Aheda, were assigned to provide assistance to the Jedi Exile in the battle that was taking place on and around Malachor V.

Unknown to the of the soldiers of the Corps, though, Revan had a terrible plan in store for ending this battle, and the war. For the last year of war, their commander had begun to fall under the sway of dark forces, which were pushing him to greater and greater extremes in his war with the Mandalorians. As the darkness inside him grew, so did his suspicion of the loyalties of those around him. No one was spared Revan's growing displeasure, even the loyal and steadfast soldiers of the R.M.C. Only a few members of the Revanchist, who were falling to the same darkness that consumed Revan, knew what he had planned for the battle of Malachor V.

When the Mass Shadow Generator went off, over 80% of the soldiers and volunteers that formed the ranks of the Republic Mercy Corps were lost to the devastation. In a heartbeat the Corps was reduced to ashes and memory. The forces aboard the Mandalorian flagship with Revan faced similar losses; only thirty sentinels made it to the escape pods as the ship was pulled into the gravity well created by the mass shadow generator.

Still not content with the devastation he had wrought, Revan continued to pursue the last of the Mandalorian cults as they fled into exile in deep space. The broken remnants of the R.M.C., though, disillusioned by their former commander's sacrifice of so many of their number in the battle, split along their ranks in how to proceed. The largest part feared Revan's fall to darkness, and refused to follow him any further. Only 200 of the R.M.C.'s number chose to follow Revan, mostly those of the Revanchist Jedi - his closest allies during the last two years of fighting.

The remaining 5000 members took refuge on the planet Alderaan, where they were given sanctuary and a place to rekindle their order - this time with a new mission. Under the leadership of General Aheda and General Mourne, the survivors began the long process of rebuilding what was lost in the previous war; providing aid and assistance to those planets and communities most devastated by conflict. These men and women rebranded the R.M.C, taking for their sigil a scored and scratched red cross. Each new planet they helped rebuild, each community they helped prop up, brought new recruits to the order, once again bolstering their ranks, close to the numbers seen during the previous war.

The Jedi Order and the Republic Senate had lost a good amount of faith with the people of the Republic over their mishandling of the war, and began to see the R.M.C. as a reminder of their failings. As this small-but-growing band of humanitarian soldiers spent the next years rebuilding worlds, their actions only emphasized the bureaucratic fumblings of the Republic's political systems. Members of the Corps often met indignation and outright hostility from Republic politicians and military leaders on the planets they were sent to serve, despite the good the R.M.C. was attempting to do for the people of those planets. This created a divide between the Republic proper and the Republic Mercy Corps. Within five years of Revan's flight from Republic space, the R.M.C. had divorced itself from the Republic military, choosing to serve the people of the Republic instead of the Republic itself.

Despite this, and their new found humanitarian mission, the R.M.C never forgot the conflicts that defined and gave them birth. To this end they continued in training new members as part of a military organization first and foremost, before these soldiers were released to their specific order within the Corps. The R.M.C's military wing, dubbed the "Blood Brothers," was founded by former Republic military solders and officers who had grown disillusioned with the Republic response to crisis in the galaxy, as well as the Corps' own veterans from the Mandalorian conflict. These officers made sure all new recruits were battle ready, no matter their role within the Corps, for when conflict would inevitably return. This fact never ceased to rankle the Republic's political and military elite, who saw the R.M.C as a militant organization in opposition to their own goals.

When Revan returned, twisted and tainted by the dark side of the Force, the R.M.C. were among the first to step into the fight against the Sith armada under his command. The atrocities Revan had inflicted on the Corps during the Mandalorian conflict were still fresh to many, and this anger was channeled into a focused determination to see him removed and his invasion stopped. Determination and drive, while never forgetting what the R.M.C had become. War was one thing. Genocide another. Divisions of the R.M.C always stayed behind to help those displaced by a battle, and mercy was shown wherever possible for enemy troops. As in the previous war, many lives were lost, but the morale of the Corps never faltered, bolstered by the knowledge that they were fighting the good fight.

Revan's invasion took an odd and fortuitous twist, though, with Revan's apprentice Malak betraying the Dark Lord, which lead eventually to Revan's return to the light. This reversal did little to rekindle the fallen Jedi to his former army though, as their paths had long since diverged. They instead maintained themselves as a force separate and alone, doing what needed to be done that politics and bureaucracy could not or would not. Once this new war was over, the R.M.C. began again to rebuild, sending the bulk of their forces to Taris to help those displaced by Malak's destruction of the planet.

This "peace" for the Republic, and the R.M.C, lasted another 300 years. During this time, as before, the Corps maintained their direction and policy, keeping themselves ready for war but building for peace. Still, as the years passed, the need for the R.M.C. diminished, and and with it, their immediate influence. The rise in recruitment capped off, and they became more an icon of a previous age. Leadership of the Corps was passed from Gen. Aheda and Gen Mourne to those who had proven their dedication and commitment to the mission, and from them to the next generation. By the time the Sith Empire reemerged from the reaches of space to attack again, a whole new regiment was in place at the Corps, one who had not seen what war could to do the galaxy, but was none-the-less ready for it.

As the Sith forces pushed into Republic space, all members of the Corps were recalled to the order's base of operations on Alderaan for deployment. Headed at this time by Generals Solara Mourne and Natalie Aheda, distant relations to the commanders who had helmed the Corps during Revan's original reign, the R.M.C was on the front lines within weeks of the start of the invasion. Fighting once again alongside the Republic Military, the Corps began attacking at the flanks of the Imperial army, cutting off supply lines and wiping out stragglers too slow to meet up with the main force of the Imperial opposition. Two brilliant strategist within the order, Sgts. Del'Nevi and Lash, quickly rose to prominence during the first months of the conflict, as their leadership in organizing these guerrilla-esque raids kept the Empire guessing without sacrificing too many of the Corps soldiers.

War is never an easy or simple thing though, and tragedy always strikes when least expected. The largest part of the R.M.C's leadership was freshly returned to Alderaan for debriefing after a string of successful raids which had isolated large parts of the Imperial army, when Darth Malgus' ruse pulled the Republic fleets away from the planet, and Alderaan was subsequently invaded. Cut off from the Republic army, and with large parts of their fighting forces scattered across Alderaan's surface, the Corps' attempts to drive back the invading army were futile. Their base of operations was overrun and demolished, and the remnants of the order were forced to take refuge in the remote mountains of Alderaan.

It was in reorganizing themselves that the order met up with the lost members of the Republic's Havoc Squad, who were also taking refuge while planning their counter-offensive. Aware that they would be unable to take on the Empire's invading army alone, Havoc and the R.M.C. combined forces to stage a series of guerrilla attacks on the advancing Imperial soldiers. Their mission was to slow down the advancing Imperial army before they could take the planet's capital city. The tactics developed by Del'Nevi and Lash proved to be the map that plotted these skirmishes, as the small but organized forces of the R.M.C and Havoc harried the Imperial army in every step, all but crippling their movements.

Meanwhile, the R.M.C.'s Order of Engineers and Strategists rallied the Alderaanian people to defend their cities, by building underground supply lines for resistance forces. Imperial soldiers began calling these men and women "Monkey Wrenchers", and the division gladly took the name as their own during the Alderaanian resistance.

Just miles outside the planet's capital, the Sith Empire, led by Darth Maglus himself, made the final push to take the planet and destroy the last Alderaanian resistance. It was here as well that Havoc and the R.M.C made their last stand. Shield generators, which up until that had kept the Imperial bombardments from touching the planet's capital, were all that stood in the way of the Empire's domination. But between them and the Empire stood Alderaan's last best hope. Greatly outnumbered and outgunned, the two allies launched their final surprise attack of the campaign: a suicide mission to delay the Empire just a little longer, and allow Alderaan's leadership to escape.

The battle was hard fought but futile, as the Sith forces cut down the R.M.C and Havoc's forces. Malgus' victory was all but secured with the final fall of the guerrilla soldiers who had plagued him, when the Republic and the Jedi Order made their timely return to Alderaan. Just as hope was lost, a contingent of Jedi knights and Republic troops, led by Satele Shan, entered the fray to turn the tide of the battle. At the zero hour, Alderaan was spared its terrible fate, and the people given time to flee the Imperial advancement while the Republic fleets returned to the planet to push the Imperial presence out.

Once again, this victory came at a grave cost for the R.M.C. For the second time in their history, the R.M.C. was almost completely devastated. Their losses in the resistance numbered in the tens of thousands, soldiers who died bravely so Alderaan's citizens could live free. It was a broken and estranged Corps that found itself left in the rubble of the Alderaan conflict, too massively weakened to continue in the war effort. For their part, the Corps withdrew its remaining troops from active operation, recalling those soliders they had left to reorganize themselves and provide support for the rebuilding of Alderaan.

Alderaanians would never forget what the R.M.C did for them, but ultimately the Republic did. Echoing the past, the shame the Republic military faced at their failure needed a scapegoat. The R.M.C. provided a convenient target. The role the R.M.C played in defending the planet went largely unrecorded and unrecognized in the galaxy at large, and no assistance was offered to the Corps by the Republic for their reconstruction and humanitarian efforts on Alderaan.

It was not too long after this tragedy that the Treaty of Coruscant was signed, and outright hostilities ended. Knowing this "peace" to be a tool for manipulation, and seeing the suffering wrought on the common people of the galaxy by the Empire, the R.M.C. once again began to build a new order of soldiers, medics, engineers and civilian volunteers. The phoenix of the Republic rose one last time from the ashes they had been left in to fight for those who could not. It was a new batch of soldiers, but one still bent on restoring hope and justice to a galaxy who could not seem to find it.

For those who had nothing, who had been left with nothing, the R.M.C offered a chance at more than desolation and hopelessness. A chance at a better future for those who would take it. They weathered and won, grew larger and stronger with each new victim who became a soldier. From the ashes they rose and spread their wings. And fought. And in a sea of darkness, a light was sparked anew.
