Let's show how the Legion Civil War began and how the Phoenix Republic became the Neo Roman Empire

Constantinople, Byzantine Empire

The citizens watched Kuroinu Knights march into their city; Mothers clutched their children tightly, Fathers and Sons glared at the Knights, Guards escorted them but warned they will not hesitate to kill them.

The Kuroinus were sent by Volt to give Roman - Shield Alliance an ultimatum, once they reached the palace and enter, guards and even servants glared at them.

"So where is the King?" The leader asked, "It's pronounced αυτοκράτορας or Emperor, Mercenary" One of the Maidens said clenching her jaw. The leader noticed she was a Dark Elf which surprised him since Dark Elfs don't leave their homeland of Garca.

Suddenly the doors open as the Kuroinus walked in and gather around a table, Augustus and Justinian sat up front while Celestine, Claudia, Luu Luu, Maia, Kaguya and Prim stepped in and took their seats with the two Emperors.

Justinian was the first to speak, "Why are Black Dogs in my Empire?" He says with a stern tone and his voice was filled with annoyance.

"Lord Volt of the Cuntry" Suddenly one of the Praetorian Guards chuckled then burst into laughter, eventually Justinian laughed as well.

"Cuntry? Cuntry? it's Country, shall I send Volt a dictionary for his misspelling and mispronunciation of a word?" Justinian asked then Luu Luu let out a hard laugh with tears in her eyes.

Justinian cleared his throat, "Continue" He says as the Black Dog adjusted himself "Has sent a ultimatum that Byzantine Empire is agree to it's unconditional surrender to the Sex Empire"

"Your asking my Empire to surrender to an Idiot false King and his little mob he calls an army?" Justinian says, "My Byzantine nay our Roman Empire was built on the blood of loyal Romans and the wisdom of my Caesar"

Augustus drank his wine, "Let me tell you a story on how my Empire came to be"

Before the main story but months after the Second Battle of Hoover Dam

The Legion was on full retreat from the NCR; They were bested once again, they fought NCR, BOS, Great Khans, Enclave Remnants, Boomers and an army of Securtions lead by a man named the Courier.

Legate Lanius was talked into retreating, the Legion despite all of their tactics and planning was all of a waste.

Edward Sallow now know as Caesar sat on his throne as he had more increasing headaches from his tumor and learning his plans to take Hoover Dam has failed.

"Goddamnit!" He screamed and slammed his Displacer Glove onto a table, Caesar grinding his teeth almost into powder.

His Legion defeated again, his own Legate forced into retreating, years of planning down the shitter. Vulpes Inculta bowed his head "Ave to Caesar" He says Caesar looked at Caesar then sighed.

"What is it Vulpes?" He asked, "My Caesar there's a young man whom looks similar to you and proclaims he's your son"

Caesar's eyes widen then spoke "What? S-Send him in!" Vulpes nodded then left his tent. Suddenly a young man who indeed looked similar to Caesar but younger, he wore scavenger clothing and held a pump action shotgun for his own protection.

"Who are you? I am the most feared man of the Mojave and you come here proclaiming to be my son?" He says, "Yeah...I am your son my name is Lucas Sallow, my mother was a tribal before you left her...I came to claim my birthright of the Legion"

Caesar wanted to order his guards to kill this young man but couldn't instead he laughed, "Welcome home...son" He said.

Months Later

Caesar's tumor became worse and worse until he was on his deathbed, Lucas now named Octavius walked to his father's bed and held his hand.

Caesar cursed out the Courier and the NCR and said even if he dies, his word is law..

law...law then Caesar went silent, Octavius covered his body with the blanket.

The Legion mourned for the death of Caesar for many days, now the Legion needs a leader Legate Lanius declared himself the new Caesar however Octavius stated he is Caesar's heir.

"Your nothing but a child who knows nothing of the Legion's history" Lanius said then Octavius narrowed his eyes "I know real Roman history you rabid dog!" Suddenly Lanius swung at him but Octavius dodged as his personal guards ran pointing their weapons at Lanius.

Lanius growled and walked away, Octavius would rename himself Augustus Caesar, within his new Legion he begin to reform them.

Slaves became full fledged works whom were paid and treated better, Slavery was abolished and technology improved from tribal weapons to advance weapons and armor.

However what truly broke the camel's back was the act Augustus wanted to form a Non-aggression pact with the NCR, Legionnaires would leave the Legion now dubbed the Phoenix Republic.

Then word came about how Lanius and Vulpes Inculta returned declaring war against him thus the Legion Civil War began.

Lanius lead his Caesar's Legion however he was nothing more then a puppet to Vulpes whom lead the Sons of Romulus, Lucius formed his Brotherhood of Mars.

Phoenix Republic - 20,000 strong; Main Goal reunite the Legion under new leadership and reforms.

Lanius's Legion: 147,000 strong; Main Goal reunite the Legion and restore the old ways.

Sons of Romulus: 200 strong; Main Goal reunite the Legion and restore the old ways and assassinate Augustus.

Brotherhood of Mars: 58,000 strong; Main Goal reunite the Legion and use advance technology to preserve the Legion.

Augustus's Republic and Lucius's Brotherhood formed a Pact to defeat Lanius, the Civil War was bloody as many Legionnaires former friends and brothers fought for their new beliefs.

Augustus made a deal with NCR, that the NCR would send Rangers to train the Phoenix Republic troops, Gun Runners sold weapons and few Followers of the Apocalypse were medics.

Durning a raid in Lanius's Legion, he came across a man whose face was bloodied and disfigured from a belt sander, Augustus had him patched and presented him power armor.

"Become my Legate and I shall grant you any desire" He told him, "I swear loyalty to you" He says and thus Legate Málleus was born.

Flagstaff

"Push forward!" Málleus shouted as he crushed his hammer into a Legionnaire then backhanded a another one.

Phoenix Republic soldiers fired a few mortar shells into the encampment, The Legion's numbers begin to fall apart as the flag of Lanius's Legion was removed and the Phoenix Republic's Flag was raised.

Lanius order his troops to retreat, Augustus walked through the camp and came across a female slave, a apart of her face was burned and she was bloodied.

At her feet was her captor, she looked at Augustus and held her knife in self defense but Augustus told her she's going to be saved.

Augustus made her Legate Ignis his first and only female Legate. Vulpes Inculta gain help from a tribe whom sent an assassin to kill Augustus but he captured, impressed by his skills and prowess.

He was made into Legate Lupus.

Durning the Civil War, Legate Lanius was killed durning the Battle of Tuscon, Lanius's Legion capitulated into the Phoenix Republic, one of Vulpes Frumentarii defected to Augustus and gain him intelligence and became Legate Memor.

Vulpes disappeared and was assumed to be dead, Augustus reached out to the Brotherhood of Mars and sued for peace and asked them to unify with them.

However it fell on deaf ears, the Civil War continue until Lucius surrender and the Brotherhood of Mars capitulated thus ending the Civil War.

A Senate was formed whom held second in command while Augustus held all of the power, the Legion Civil War many slaves became soldiers or members of the Senate.

The Phoenix Republic transformed into the Neo Roman Empire.

Back in Eostia

"As you see how many lives lost and now my Empire grows even if I split it into two, my Empire is stronger then you think and my alliance with the Seven Shields only strengthens it more, we will not surrender until Volt and his Alliance is destroyed or sues for peace" Augustus snapped his fingers as the Guards grabbed the Kuroinus.

"Get them out of my sight..." He says with his eyes turning a bit dark.
