The Aurelian War was a large-scale conflict between the Federal Republic of Aurelia and the Democratic Republic of Leasath.


Prior to the Aurelian War, a civil war broke out in Leasath when their economy collapsed at the time when the government were planning to export future arms industry markets all over the world. The result of the civil war was unknown, but General Diego Gaspar Navarro managed to unite the remaining troops. Its neighboring country, Aurelia aided the country's people with vital supplies.


In October 2020, the Democratic Republic of Leasath invaded the Federal Republic of Aurelia. Aurelia's border defenses immediately fell to the Leasath forces. Within just a few days, 60% of Aurelia was under Leasath control. Phuku Lagolla Air Force Base, located to the south-west of Griswall, was one of the last military bases still under Aurelian control. To defeat Aurelia once and for all, Leasath dispatched several bombers to destroy the base. But they were intercepted and destroyed by Falco Squadron, an experimental aircraft testing squadron, the leader of which, Falco 1 quickly gained the nickname, the southern cross. After, Leasath launched an attack on army base Sallqa, which the Aurelian army had made their field HQ, but it was defeated by Falco Squadron. Leasath then launched a naval invasion on the port of Challwa, located to the south of Griswall, but it was defeated by Falco Squadron.


Leasath's invasion was now running out of steam. As revenge for their previous defeat, the Leasath Air Force attempted to destroy an army base Sallqa, but they were defeated by Falco Squadron. By now the Aurelian's war strategy was maintaining a supply line between Sallqa and Griswall. Giving up on trying to destroy Sallqa, the Leasath Air Force instead decided to cut off this supply line. They sent a number of fighters, including the legendary Chimera Squadron, but they were all shot down by "The Southern Cross".

The Tide Begins To Turn

With Leasath's invasion running out of steam, Aurelia decided to go on the


offensive. Falco 1 was sent to destroy several supply warehouses protected by an anti-aircraft system and succeeded. Aurelia then decided to move a fleet of undamaged warships from Port Patterson, where they would defend Griswall. Leasath sent a huge fleet to stop them, but with the help of Falco Squadron, the Aurelian fleet made it out of port. With defeat now starring them in the face, Leasath high command decided to make a difficult decision. They deployed the Gandr, an experimental prototype of the Gleipnir, to destroy the fleet. Intercepting the Aurelian fleet, the Gandr fired a single SWBM, which destroyed the entire Aurelian fleet. Falco Squadron immediately engaged the Gandr. Despite having to fight through the Chimera Squadron, and dodging numerous SWBMs, Falco Squadron destroyed the Gandr. Despite that, the loss of the naval fleet was a crippling blow that Aurelia didn't manage to recover from until the end of the war. Not long after, Griswall fell. Things seemed bad for Aurelia.

Skies of Deception

The Leasath Forces were led by Commander Diego Gaspar Navarro, during their full scale offensive against Aurelia.The Leasathians were not only large in numbers but also possessed large numbers of state-of-the-art unseen equipment, vehicles and weapons. By October, after only 10 days when they declared war, they now invaded 95% of Aurelia.

A large Leasath bomber group was launched in order to destroy one of the last Aurelian Air Bases at Cape Aubrey peninsula in North West Aurelia. Aurelian ace Gryphus One was scrambled with an entire fighter squadron and successfully managed to intercept the bombers. After the Leasath aircraft were shot down, however, the Gleipnir over the Puna Plains launched an SWBM shortly after decloaked from its optical camouflage system and wiped out most of the Aurelian aircraft with only Gryphus One, Five and Six in the skies afterward. The last stand against Leasath's brutal blitzkrieg was deemed 'futile' by several newspapers.


When the news of the near decimated Gryphus squadron at Aubrey Air Force Base, it was claimed resistance was futile by some newspapers, as Aurelia's final troops surrendered. However, not long after Gryphus One and two Aurelian fighters were launched for a surprise attack to Puna Base, which was a great success and the Aurelians managed to get hold of vital supplies. An Aurelian Army assault team then moved to retake Port Patterson for their forces, in an attempt to mount a counterattack with the help of the Gryphus Squadron. Despite a Leasath amphibious fleet preparing to land vehicles and tanks, it was sunk thanks to Gryphus squadron. The Gleipnir had returned to a replenishment base in Terminus Island, Southern Aurelia.

Gryphus Squadron was then deployed to Kingshill to stop a Leasathian counterattack to recapture Port Patterson. The deployed forces, including the elite Miller Unit, were all destroyed.

Gryphus One was then deployed to Stand Canyon in order to defend the Davis Unit, which were being cut off from the main force. He protected the ground unit while it was being attacked by Gleipnir's SWBMs. The unit was successfully defended. After this, the Gleipnir has flown to Santa Elva.

Gryphus Squadron was deployed to Terminus Island. Alongside an allied diversionary fleet, the squadron was tasked with destroying a Leasathian fleet while the Aurelian submarine, Naiad, travelled to the area where a friendly scientist was being held captive. When the fleet was destroyed and the Naiad reached the area, enemy E-767s were deployed to detect the submarine. They were ultimately destroyed by Gryphus One. After the commandos rescued the scientist, the Naiad had struck a undersea mine, forcing it to surface. The control system was also destroyed, which put the submarine on a collision course towards an iceberg. At this point, Leasath had deployed stealth bombers to destroy the Naiad. Gryphus Squadron successfully destroyed the iceberg and the incoming bombers.

Gryphus Squadron was then deployed to Santa Elva in order to destroy the Gleipnir once and for all. The squadron first destroyed the optical camouflage system, which rendered its stealth capabilities useless. Gryphus Squadron then targeted the SWBM ports, which dealt severe damage to the Gleipnir. The crew of the airborne fortress made one final stand, which was using the Shock Cannon on the city. Gryphus One dealt the final blow at the Gleipnir by destroying the cannon. The Gleipnir, whose engines were failing, finally crashed into the Lenal River.

With the loss of the Gleipnir, Aurelian forces began to push the Leasath forces back on all fronts. The largest Aurelian Air Force base was re-taken, and the Nevera Jammer at Mount Nevera were destroyed.

However, this was at the expense of defenses at the captured and fortified Aurelian capital, Griswall, by a technology airlifted from Monte Breeze Industrial Area. Despite that, the Aurelian forces headed by Gryphus One, now known by the Leasath military as "Nemesis", launched an operation to retake their capital, Griswall. However, Leasath forces had set up Meson Cannon on Atmos Ring within the capital and the plasma particle cannons fired upon the Aurelian forces relentlessly. During the attack, Leasath commander Diego Navarro had fled Griswall and retreated to nearby Leasath territory. Meanwhile, the Meson Cannon, along with all Leasath forces were destroyed. The Aurelian capital was retaken. Soon after this, all Leasath forces were pushed out of Aurelia.

After a few days of regrouping and reestablishing their flow of supplies, the Aurelian military was on the move once again, this time to stop Diego Navarro once and for all. General Navarro and his remaining forces had fled to the nearby Danern Straits. It was confirmed that a secret Leasath super weapon was under development there. Though no details were known at that time, it was believed that this weapon could be mass-produced and posed to be a large threat to all Aurelian forces.

End of Deception

Gryphus One and a fighter squadron flew to the Danern Straits and destroyed a large research facility in Cobalt Cave, which was developing technology to make this new super weapon even more powerful. The technology would have used microwave energy to target an aircraft's fuel tank and force it to ignite. Unfortunately, this let Leasath's elite aerial fighter unit known as the Alect Squadron to fly to Archelon Fortress in S-32s (Su-47 Berkut prototypes) within the Danern Straits, where Navarro and this new super weapon were waiting.

When Gryphus One and the Aurelian forces reached the area, they were attacked by the Alect Squadron in an aircraft known as the 'Fenrir' equipped with optical camouflage. The advanced fighters, Fenrir, were Navarro's reason for initiating a war between neighboring Aurelia. It was found that the point of the war was to gather battle data from the Gleipnir, steal funds and resources from Aurelia and develop the Fenrir in order to sell it to nations around the world.

Gryphus One was attacked by the entire Alect Squadron at once, and in an amazing feat of bravery, he destroyed all Alect Squadron Fenrirs. Diego Navarro then activated a reproduced version of the Shock Cannon seen on the Gleipnir and attacked the Aurelian aircraft. Gryphus One destroyed the Shock Cannon, flew into the Archelon Fortress, destroying the Fenrir prototypes and Navarro's hopes of exporting the fighter.
