Raid on Liberio

The Battle of Liberio is an ongoing conflict between the military of Marley against the invading Attack Titan and the Survey Corps of Paradis.

Nations in Decline
The unceremonious near-defeat of the Armored Titan at the hands of the Mid-East Allied Forces' anti-Titan artillery served as a grim reminder to the Marley military that the era of the Titans was coming to an end. Following Marley's victory over the Allies, the leaders of the Marleyan military gathered to discuss the apparent threat to their global influence. Commander Theo Magath, noting the Allies' superior navy in the recent war, was of the opinion that reliance on the power of the Titans could not guarantee victory in ground-based warfare any longer, especially given the rising advent of military aircraft which would render the Titans completely obsolete in battle.

At this time, Warchief Zeke Yeager proposed the plan to focus Marley's efforts on taking the Founding Titan in order to gain an advantage in Titan-based warfare while simultaneously making efforts to improve conventional weaponry. Since his term as the Beast Titan had approached its final year, Zeke desired to complete this objective himself in the short time he had left to live before passing his power on to Warrior cadet Colt Grice. This proposition appeased General Calvi, who assured Zeke that his plan would be passed on to the governmental party of Marley. However, there were other matters on Zeke's mind related to the imminent end of the Titan era.

Upon returning to Liberio, Zeke gathered the Warriors together to discuss the fate of the Eldian race. Given the declining practicality of Titan weaponry, this decline would inevitably apply to the Eldians who served as the basis for the Titan power. Once the Titans outlived their use, the continuing existence and guaranteed safety of the Eldian race would be at great risk in Marley and the world at large.

The Tybur family, a family of Eldian aristocrats in Marley and the keepers of the War Hammer Titan, would resolve this threat by acting as the spokespeople for both Eldia and Marley. During an upcoming festival being held in Liberio, journalists and ambassadors from around the world would gather to hear the words of the Tybur family, who would mark Paradis as the greatest threat to world peace and would guarantee the island's fall within a year. With this strategy, the security of the Eldian race and Marley's continued dominance over the world would be guaranteed.

A New Helos
Soon afterwards, the Tybur family arrived in Liberio where Commander Magath met with Willy Tybur, the head of the family. Together the two discussed the declining state of their nation, comparable to the empty legend of Helos the slayer of the Devil, and the suffering of the Eldian people, both crises which the Tybur family were in some way responsible for.

As Magath had suspected, the Tybur family had been acting as the true ruling head of Marley, though in matters of both Marley's military policies and the subjugation of the Eldians the Tyburs remained uninvolved observers. Wishing to right these wrongs, an alliance was struck between Commander Theo Magath and Lord Willy Tybur to save Marley and Eldia from destruction. Throughout the next month, as preparations for the grand Liberio festival were underway, Tybur and Magath began conspiring against the top brass of the Marleyan military, the greatest threat to Marley's advancement and the peace of the Eldians. By Magath's investigations, the leaders of the Marleyan military had become "aged" like the structure of a poorly-tended home requiring large-scale demolition. Given this necessity, Commander Magath was placed in a position that would make him the general of Marley's military forces should the need arise. However, despite the military's needed demolitions, some the structure's "posts" were still usable and had informed him of rats that had infiltrated the home.

Infiltration
At some point during the Marley Mid-East War, Eren Yeager had infiltrated Commander Magath's Eldian Unit disguised as a soldier named "Kruger", presumably acting on his own decisions rather than under orders from his superiors. In the initial days after the war, Eren kept a close watch on the Warriors, particularly Reiner Braun, and began to take pity on the Eldians for the subjugation they faced on the mainland.

After returning to Liberio, Eren faked psychological trauma and was sent to recover with other damaged soldiers in a hospital. At this hospital, Eren met Warrior cadet Falco Grice, who became his close acquaintance. Claiming to send correspondence to his family, Eren used Falco as a means to deliver messages to his allies in the Survey Corps who were searching for him. This correspondence would continue over the course of the next month leading up to the Liberio festival. While the details of the infiltration were muddled, Commander Magath and Willy Tybur were well aware of the spies lurking in their homeland. Given the knowledge that 32 scout ships sent to Paradis had disappeared in the past three years, it was suspected that the forces of Paradis were at work.

Sensing an opportunity for Magath's rise into power, Willy suggested clustering the undesirable authorities of the Marleyan military together during the upcoming production to serve as bait for whatever attackers may come forth. The party of Marley would grant Magath full authority to select any officers he desired to be the authority in his newly rebuilt military.

Magath was wary of the plan, noting that many innocents would die and Willy Tybur's life would be at great risk as well should the festival production come under attack. These would be necessary losses in Willy's eyes, who believed the world would not take his side if he escaped any disaster alone. With the bait set, the festival was ready to proceed.

The Curtain Rises
On the night of the Liberio festival, the preparations made between Magath and Lord Tybur were underway. As planned, General Calvi and the leadership of the Marleyan military were clustered together near to the stage while ambassadors and journalists from across the world were gathered to witness the stage production planned by Willy Tybur. From the rooftops, Commander Magath oversaw the stage production while receiving news of suspicious activity from his subordinates. Anti-Titan artillery was placed on the rooftops to be fired at the closing of the production.

At this time the Survey Corps began to act from the shadows against Marley, sending a spy to trap Porco Galliard and Pieck, the Jaw Titan and Cart Titan respectively, away from the site of the production. This same spy sent Zeke Yeager away from the festival area, though Zeke was not taken away with Pieck and Porco. Suspecting ill intent, Pieck informed her Panzer Unit of the soldier's strange behavior, telling them to follow her. After being led indoors, the spy trapped Pieck and Porco in a deep pit where they could not transform into their Titans. News of their disappearances soon reached Magath, who mobilized the reserve troops. Elsewhere, Eren requested for Falco to lead Reiner Braun to him in a basement room behind the Liberio stage, leaving the audience devoid of any Warrior Titans. Shocked to see Eren in his hometown after four years, Reiner readily listened to Eren's threat of transforming in the basement and murdering the civilians in the building above listening to the production. At this time, Willy Tybur's stage production began.

Recounting the atrocities of the ancient Eldian Empire, Willy Tybur reminded his audience of the horrors brought by the Titans and Marley's triumphant victory over the Eldians in the Great Titan War a hundred years ago. However, Willy Tybur used this opportunity to reveal the truth of the Great Titan War which he learned upon inheriting leadership of the Tybur family: Eldia's downfall came from within at the hands of King Karl Fritz who conspired with the Tybur family to destroy Eldia and place Marley in power. With the truth of Eldia's downfall made public, Willy declared Paradis to be the greatest threat to peace in the world: the Founding Titan that had guaranteed the pacifism of the Walled Kings was now in the hands of Eren Yeager, who could use the Founding Titan through methods unknown to Marley. In this desperate time, Willy Tybur called for the union of the world's armies to end the threat of Paradis and usher in a new age of peace. Understanding who his true enemies were, Eren saw himself in Reiner and took pity on him. Taking Reiner's hand, Eren committed to continue his advance until his enemies were destroyed.

First assaults
With the eyes of the world on him, Willy Tybur denounced the devils of Paradis and made a declaration of war. Behind the stage, the Attack Titan burst forth and crushed the stage, killing Willy Tybur and eating him. Chaos erupted in the audience as debris fell from above, crushing many to death. Seeing the Marley military officials seated nearby, the Attack Titan lunged into the stands, destroying General Calvi and the others of the top brass. As the survivors in the audience fled for their lives, Willy's sister emerged from the ruined stage to transform into the War Hammer Titan, though her Titan was quickly intercepted and beaten into the ground by the Attack Titan. Commander Magath took charge of the situation, ordering for his men to report to their battle stations as the War Hammer Titan gained the upper hand by impaling the Attack Titan on a massive spike. While the Titans dueled, Pieck and Porco were rescued by the Panzer Unit and prepared to equip the Cart Titan for battle. At this time, the Warriors noticed enemy soldiers flying overhead on vertical maneuvering equipment. The Attack Titan struggled to evade the War Hammer's strikes and the barrage of artillery fire.

Koslow worried over the possibility of losing the Founding Titan, though Magath insisted that ridding Paradis of the Founder would be more beneficial than Marley attempting to gain it. The Attack Titan was quickly caught and defeated by the War Hammer Titan, who prepared to kill Eren Yeager after he was forced to emerge from his Titan's nape. When asked for his final words, Eren called for Mikasa Ackerman to strike at the War Hammer from behind. Using a barrage of Thunder Spears, Mikasa felled the War Hammer before reuniting with Eren while the soldiers of the Survey Corps engaged in a firefight with Magath's troops. Despite the heavy damage done to the nape, the War Hammer Titan regenerated its body and retaliated, forcing Eren and Mikasa to abandon the Attack Titan. Mikasa continued to attack the War Hammer while Eren formulated a new strategy.

Commander Magath's troops relocated to an abandoned building where Magath called for backup from the vigilance training division of the army and the 30,000 troops stationed in the navy offshore. Meanwhile, the arriving Survey Corps continued their assault on the Marley military, killing rooftop soldiers and bombing Magath's troops in their hideout. Floch began incinerating entire buildings in the process, to the dismay of his comrade Jean Kirstein. While civilians evacuated the internment zone, the Survey Corps soldiers killed any inbound Marleyan troops, leaving small lights on top of cleared buildings. Once the area was clear, the Survey Corps soldiers regrouped at the plaza with Eren and Mikasa, joined by Levi Ackerman. Commander Magath and his troops made their way to the plaza as well, along with Warrior Cadet Gabi Braun who had survived the outer firefights. Discovering the War Hammer's ability to remotely control the Titan, Eren discovered the crystal underground holding Willy Tybur's sister, severing its connection to her Titan and preparing to eat it with his Attack Titan. At this time, Galliard's Jaw Titan arrived at the scene, attempting to eat Eren Yeager and the Founding Titan. Levi cut at the jaw muscles of the Titan, preventing it from biting through, just as Pieck's fully-equipped Cart Titan and Zeke's Beast Titan arrived at the scene. Having regenerated its connection to the ground, the War Hammer Titan generated a tree-like structure impaling the Attack Titan. The Titans regrouped in the plaza readying to annihilate the invading Survey Corps.
