The Great North American War of the Myths: E Pluribus Unum (第五特異点 北米神話大戦 イ・プルーリバス・ウナム, Hokubei Shinwa Taisen?), The White Cloth of Steel (鋼鉄の白衣, Kōtetsu no Hakui?), is the Fifth Singularity (第五特異点?) of the seven visited during the Grand Order to solve the Human Order Incineration Incident in Fate/Grand Order. Located in North America, A.D. 1873, its Humanity Foundation Value was A+.
SettingEditMedb created a twisted version of Cù Chulainn as her wish for him to rule alongside her as her king. Leading an army of warriors that she can endlessly produce, Medb and her Servants began to conquer America to create a new Celtic nation; killing everyone who isn't Celtic. The Americans attempted to repel the Celts, but they were easily overwhelmed by the Celts.
Edison took control of the broken American armies, becoming their President-King. With the aid of Edison's robots, the Americans were able to hold their ground against the Celts, yet they were still unable to completely defeat them. However, his mind affected by the accumulated thoughts of the presidents, Edison became so obsessed with winning the war that he turned into a despot. He had the army force civilians to work in his robot factories.
Due to the actions of both the Celts and Edison, Geronimo formed a resistance against both of them. His resistance eventually got into a skirmish with Cù Chulainn, who easily wiped out the resistance soldiers and gravely injured Rama (a member of the resistance) with Gaé Bolg. By the time Chaldea arrives, the Celts have conquered the eastern half of America while the Americans remain in control the western half.
Ritsuka and Mash arrive in the era in a forest. They come across a battle, with one side using robots resembling those of Charles Babbage. The robots mistake Ritsuka and Mash as enemy reinforcements and attacks them. After destroying the robots, the pair are attacked by the opposing side when the other retreats. Though they’re able to win, Ritsuka is suddenly hit by cannon fire and knocked unconscious.
Ritsuka later wakes up in a tent, being treated by a woman. She prepares to amputate their arm when Mash convinces her not to. Mash then heals Ritsuka's wounds with a magic scroll. Mash explains they're in the rear base of the American Independence Army. She reveals the woman is a Servant and her True Name is Florence Nightingale. She tries to ask for her help when the camp comes under attacked. Ritsuka and Mash go out to repel the attack, followed by Nightingale. The group eventually face off against the enemy commanders, Diarmuid Ua Duibhne and Fionn mac Cumhaill. They defeat Diarmuid, but Fionn heals and joins him in another fight. The group defeat them, but Nightingale runs back to camp when she sensed the wouned were under attack. Diarmuid and Fionn are forced to retreat when a Servant with reinforcements arrives.
Later, a woman followed by an entourage of mechanized soldiers reprimands Nightingale for leaving her post. She reveals America is in a war between East and West; East being the Celts, West beging the United Western States. She then introduces herself as Helena Blavatsky. She refuses Mash's request to let Nightingcale help them resolve the Singularity, but Nightingale ignores her orders. Left with no choice, Helena orders her soldiers to subdue the group. They destroy the robots, but Karna arrives and attacks them with Brahmastra.
The group later wake up, having been knocked out by the shockwave created when Mash blocked Brahmastra. They're being transported to Denver, where Helena's king will try to convince to join him. The group eventually reach Denver, where a castle was built when the Celts took the White House.
Inside the castle, the group meet Thomas Edison, President-King of the United States. Edison asks for Ritsuka’s aid in defeating the Celts. Before he took command, the Celts outumbered the Americasns. He evened the odds with his robots, but he lacks enough Servants to turn the tide. He declares he'll have civilians work 20 hours a day to keep the mass production of his robots going. He then reveals he will use the Grail's power to create his ideal America on a different timeline. This act could destroy the other eras. Nightingale tries to attack Edison, but Karna restrains her. Edison then gives Ristuka three minutes to make a decision. Ritsuka refuses to join, so Edison has his robots subdue the group. Overwhelmed by the sheer number of robots, the group are sent to the underground prison.
In the prison, Ritsuka’s Magical Energy link with their Servants is neutralized by Helena to prevent their escape. Later, as the group struggle to escape, a Servant suddenly appears before them. He borrowed another’s Noble Phantasm to avoid Karna and introduces himself as Geronimo. He busts the group out of their cells, and helps them escape. Along the way, he reveals he is a part of a resistance against Edison and the Celts with three other Servants. He asks the group to join him. The group finally escape after defeating Karna.
The group arrive in a deserted town serving as the Resistance’s hideout. Geronimo asks Nightingale to heal a Servant member of the Resistance. The others notice his heart is severely damaged. He introduces himself as Rama, and Gáe Bolg caused his wound. However, Rama cannot be healed unless Gáe Bolg's curse is removed. Since fighting Cú Chulainn to destroy his spear is near suicidal, the group agree to find a Servant related to Rama to remove the curse. Rama suggest his wife, Sita, who is imprisoned somewhere. The group then discuss on how to deal with the seemingly endless armies of Edison and the Celts. Celtic soldiers are born continuously from their queen, while Edison’s robots are mass produced. The group to assasinate both leaders to stop their armies from growing. They then leave to recruit Servants to aid them.
During the journey, Geronimo explains how the Western American citizens are forced to work on the mechanized infantry mass production lines. The group come to Lubbock, where two Archers, who are members of the Resistance, are being besieged by Celts. They help them to repel the attack. The two introduce themselves as Robin Hood and Billy the Kid. After Mash gives them the details, Geronimo suggests the group needs Saber and Lancer to help. Robin confesses he met two problematic Servants who fit the aforementioned classes earlier.
Later, the group arrive at the entrance of Dallas, where one of the Servants Robin met is located. After defeating some unexpectedly weak Celtic soldiers, they hear a disturbing song that Ritsuka, Mash, and Robin recognize. Entering the town, they meet with Elizabeth Báthory as she continues her singing. They deduce that is the reason the soldiers they were so weak. Mash convinces Elizabeth to join them by saying it will help promote her art.
Passing through a forest to Alexandria, the group witness Nero Claudius being confronted by Fergus mac Róich, who was sent to kill her. Robin uses No Face May King to ambush him when Nero reveals his presence. The others then arrive to defeat Fergus. Before disappearing, Fergus tells Rama that Sita is being held on Alcatraz Island.
Later at night, Geronimo informs the others that the Celtic stronghold is the White House. He states the group will split into two. One with Nightingale to rescue Sita, and another to infiltrate the White House and assassinate the Celtic queen. Geronimo decides Ritsuka and Mash will accompany Nightingale and Rama; Nero convinces Elizabeth to go with them. Taking the others with him, Geronimo is given a communication device by Mash. The next morning, the group split into their respective teams to carry out their missions.
Ritsuka’s group arrive at the coast near Alcatraz. They then take a boat to the island. Coming ashore on the island, the group head for the prison while slaying wyverns sent by a Servant. Arriving at the prison, they confront the Servant, who introduces himself as Beowulf. The group slay his dragon, then fight him. After he's defeated, Beowulf allows them to enter the prison.
Inside the prison, the group meet Sita as Rama faints from his wound. Sita reveals Rama is afflicted a curse that keeps them apart, even as Heroic Spirits. Either will be summoned as Rama never to be summoned simultaneously, though the Singurality is an exception. Nightingale heals Rama’s wound, but Gáe Bolg’s curse still persists. Sita then sacrifices herself by taking the curse into herself to dispel it. After Rama wakes up, the group leave to rendezvous with Geronimo’s group.
At Washington, Geronimo's group go to assassainte the Celtic queen, Medb, during a parade. They sneak up her with No Face May King, then isolate her in Nuptiae Domus Aurea. However, Cú Chulainn Alter suddenly appears when Medb calls for him and attacks Nero. Confused by his strength inside the theater, the group learn Medb created him from her wish on the Grail for Cú Chulainn to be a strong and wicked king who’ll stand beside her. The group fight him when Arjuna arrives. Cú Chulainn Alter fights Nero alone while Medb and Arjuna fight the others. Geronimo orders Robin to take the communicator and escape. After he escapes, the others proceed with their battle.
Meanwhile at Alcatraz, Ritsuka’s group escape the prison when they’re confronted by Fionn and Diarmuid. After killing the pair, they receive a transmission from Robin. He informs them that the assassination plan failed. He tells them to meet with him at the abandoned United Western States base he is heading for. Receiving his coordinates, the group leave to meet with him.
As Geronimo's group continue their battle, Geronimo unleashes Tsago Degi Naleya on Arjuna. Arjuna destroys it with Agni Gandiva, then kills Billy. Medb kills Gerenimo after he predicted she'll die soon. She then orders Arjuna to chase after Robin After her theater collapses, Nero is finished off by Cú Chulainn Alter.
Ritsuka‘s group eventually locate Robin to see him under attack by Celts. After they help him, Robin tells them of the failed assassination of Medb. He also says a Servant saved him from Arjuna and Cú Chulainn Alter’s pursuit. That same Servant then introduces herself as Scáthach. She originally intended to destroy the era until deciding a human needs to end the war upon seeing Ritsuka. She refuses join the group, but offers her help all the same. She admits even she cannot defeat Cú Chulainn Alter, as his power granted by Medb’s wish rivals her own. She could destroy the Grail along with Medb, but that would delay the repair of the era greatly. While fighting more Celts, the group come across Li Shuwen. He fights Mash to a standstill to test the group's strength, and to convince Scáthach to duel him. He refuses to join the group, though he's an ally. He then leaves, saying Edison seems to be possessed. The group then depart Denver to confront Edison.
Travelling back west, the group arrive at Kearney while its being attacked by Celts. They capture a few of them at Robin's behest. Ritsuka and Robin take the prisoners to a mechanized infantry robot. Robin claims he is Second Lieutenant Anderson Komadori, and he is transferring prisoners to headquarters. As the prisoners are Celts, the robot allows him to pass. The group proceed to Edison’s castle.
The group breakthrough the robot guard, and enter the castle. They fight Karna until Edison calls him back to the throne room. There the group defeat Edison, along with Helena and Karna. Edison refuses to give up and tries to drink a elixir to transform himself, but Karna throws it on the floor. Nighingale informs him the Celtic army is infinite while his is limited. It is then revealed that Edison’s tyranny resulted from his mind being affected by accumulated thoughts of the presidents entrusting him with America’s future. Edison is eventually convinced by everyone to join the group. 
Later, the group strategize on how to defeat the Celts. The Celts will be invading Denver via the northern and southern routes. If thy conquer any more of America then the era will no long withstand its separation from reality and collapse. The group eventually decides with a two prong attack with two armies to attack along the northern and southern routes. One army will hold its ground against the Celts while the other will breakthrough to the White House. The group leave the decision of what Servants will go with what army to Ritsuka. 
The next day, Ritsuka announces their decision. The north army will have Elizabeth, Robin, Edison, and Helena. The south army will have the others. The north army then departs to await the battle three days from now at dusk. After testing Ritsuka and Mash's resolve, Scáthach orders Rama to lead the army since she isn’t joining the battle. Instead, she will monitor Medb and Cù Chulainn Alter, who she’ll stop from entering the frontlines. After she leaves, the south army start their advance toward Washington.
As the south army arrive in Montgomery, Mash relays a message from Karna that his vanguard defeated an enemy vanguard yet a few breakthrough. After defeating the stragglers, the south army continue their advance when a scout reports the Celtic army ahead is led by Arjuna. Rama orders him to tell all troops not to engage with Arjuna. Arjuna orders his troops to attack the south army while he fights Karna. The south army and Celtic army clash while Karna and Arjuna fight. Eventually the south army defeat the Celtic army, while Karna and Arjuna’s battle continues. However, Karna is struck from behind by Cù Chulainn Alter. He reveals he killed Scáthach, and fights the group. He prepares to kill Mash when Merlin, projecting himself through Fou, traps him in an illusion. Karna takes advantage of that to launch Vasavi Shakti at Cù Chulainn Alter with the last of his strength. However, it wasn't strong enough to kill Cù Chulainn Alter, and Karna disappears. Cù Chulainn Alter then retreats to Washington to heal his wounds. The group tries to chase after him when Arjuna stops them to fight them. After defeating him, Mash asks Arjuna to join them, but he declines and leaves. The south army then continue their advance.
As the south army engage with incoming Celtic forces, the details of the fight between Cù Chulainn Alter and Scáthach are revealed. During their fight, Scáthach and Cù Chulainn Alter cancelled out each others' Gáe Bolg. Scáthach activates Gate of Skye to pull him into the Land of Shadows, but he activates Curruid Coinchenn to prevent that. He then stabs her, and she escapes to the Land of Shadows to recover. There she meets Li Shuwen and asks him to help the north army until she recovers. Li Shuwen complies with her request. On the northern front, the north army continue their battle against the main Celtic army. Beowulf arrives and fights Robin and Elizabeth, while Helena and Edison fight the Celts. Fortunately for Robin and Elizabeth, Li Shuwen arrives and engages in a fistfight with Beowulf.
Meanwhile, Ritsuka’s group eventually reach Washington. They slay Medb's summoned monsters, and chase after her when she retreats to the White House. At the White House, the group see it was transformed from its original state. Inside, they fight Cù Chulainn Alter and Medb. Though mortally wounded by Brahmastra, Medb uses the Grail to summon Clan Calatin to attack the north army. She then gives the Grail to Cù Chulainn Alter before disappearing. Cù Chulainn Alter’s Magical Energy weakens due to the self-correction of the era strengthening with Medb now gone. The group then fight Cù Chulainn Alter.
At the same time, the north army continue to struggle against Clan Calatin. Edison attempts to self-destruct himself by overloading his Noble Phantasm to protect the others. He’s stopped though by the sudden appearance of Nikola Tesla, who arrived to save the era to repent for his actions in London. Realizing their attacks are effective, Tesla and Edison unleash their Noble Phantasms simultaneously to seal Clan Calatin off. Arjuna then arrives and sacrifices himself to launch a restricted Pashupata to destroy Clan Calatin.
Meanwhile, in the White House, the group defeat Cù Chulainn Alter. However,her uses the Grail to incarnate himself into Halphas. Nightingale uses Nightingale Pledge to heal the group. After defeating Halphas, Ritsuka and Mash return to Chaldea with the Grail.
