The United Realm War

The War of Westeros was a major military conflict taking place predominantly in the Crownlands between the majority of the realm, mainly led by House Lannister, House Pemford, House Dayne, and the crown House Targaryen. The war started in 322AB, finishing in 326AB after House Targaryen were beaten by the largest rebel force ever recorded. 
== Prelude ==
During the latter stages of the Dragon's Vengeance in 314AB, immediately after House Dayne's defeat at the hands of House Targaryen under King Aegon VIII Targaryen, or Sahsook, House Lannister intervened in the war in an attemt to regain King's Landing and restore the Dayne monarchy. Soon after, several Westerlands and Dornish armies where at the King's Landing gates. However, the battle would result in a humiliating 5-0 defeat for House Lannister and Dayne during the Massacre of the Lionstar, resulting in the Dayne and Lannister armies being crushed and forced to leave the Crownlands. However, House Dayne and Lannister were still vengeful, and were waiting for the right opportunity to strike.
Soon after, House Egen declared war for the crown in 314AB, during the Strike of the Birds, only two years after being named hand. This war was long and fierce, with House Targaryen, hands House Pemford, and the rising powerhouse House Velaryon defeating the rebels in 319AB. However, with rising disapproval for House Targaryen, even from their hands House Pemford, cracks were beginning to show. This disapproval was from House Targaryen's authoritarian rule, amid low engagement with the community. Another rebellion was brewing. 
== A Roaring Declaration ==
Soon after the attack upon House Blackfyre, Lord Tywin Lannister declared open rebellion against King Jaehaerys III Targaryen, or chrispell. Lord Tywin cited Targaryen's reign of 'Fire and Blood' as being the main reason, causing the realm to exist in a state of bloody despair. Lord Adrian Lorch, or MarsAthame, soon followed his liege into declaring, as well as Lord Harys Swyfe, or YANKEEMOXXY. House Sunglass also declared.
However, other houses were slow to declare support for the rebellion, with Lord Baelon Targaryen (who later became king in 325AB), responding to the Lannister claims regarding Blackfyre and the state of the realm. House Reyne, House Cinema, and House Pemford all backed Targaryen.
== Blackfyre Mistreatment ==
Battle of Sow's Horn (Targaryen vs Blackfyre & Horpe) and Battle of Wode Lands (Targaryen vs Blackfyre)
A major driving force leading up to the rebellion was House Targaryen's treatment of their sworn vassal, House Blackfyre. In 321AB, Lord Daemon Blackfyre, or iAduriteX had pledged to become House Targaryen's vassal and alliance, in hope of a united Crownlands.
However, by 322AB this alliance was not fruitful, with House Targaryen attacking Blackfyre's holdings, due to Blackfyre's desire to remain neutral during the upcoming wars, and Targaryen's suspicions of conspiring to rebel. House Blackfyre beat the outnumbered Targaryen force 3-0 at the Battle of Sow's Horn, with the assistance of House Horpe, but lost 3-0 at the Battle of Wode Lands. As a result of the Targaryen attack, Blackfyre pledged their support to House Lannister. These battles are considered to those which ignited the war. 
The treatment of House Blackfyre proved to be a catalyst for rebellion, with Lord Tywin Lannister, or SSWEEEEjr, pledging to stand by Blackfyre against the tyranny of House Targaryen. House Clegane, House Baratheon, House Morrigen soon after pledged their support to House Blackfyre, thereby declaring hostility towards House Targaryen.
== The Realm Declares ==
Soon after Blackfyre's damning condemnation of Targaryen, the small amount of faith in House Targaryen seemed to all but falter. The paranoia between Targaryen and Pemford had finally resulted in turmoil between the two houses, with House Targaryen replacing Lord Hand Hayden Pemford, or Northmathr, with Lord Hand Daemon Velaryon, or kas_g.
Lord Arthur Dayne, or DoMeat, declared himself King Arthur III Dayne, announcing House Dayne's conquest. House Pemford also declared war. Official declarations soon followed from House Hersy, House Blackfyre, House Blackwood, House Royce, House Bulwer, and House Horpe.
The crown were only supported by House Velaryon and House Templeton.
== The Riverlands Rush ==
First Siege of King's Landing (Targaryen vs Pemford & Blackwood)
House Pemford and House Targaryen were once close allies, banding together due to mutual interests in defeating House Egen. However, with the Strike of the Birds long over, relations between Pemford and Targaryen had deteriorated, due to interests no longer being aligned, as well as Targaryen's authoritarian paranoia. Consequently, The Pemford Quadrumvirate now stood as the biggest threat against House Targaryen.
In 323AB, with the ever faithful Riverlands Coalition firmly behind Pemford, House Pemford and House Blackwood besieged King's Landing from the front, full of confidence and optimism of their success. The realm firmly believe House Pemford has the skill to defeat House Targaryen. However, after several hours of battle, with several rounds voided for suspicious activity, House Targaryen decisively defeated the Riverlands force 5-1. The Riverland Coalition were forced to retreat and regroup back in the Riverlands.
== The Westerlands Charge ==
Second Siege of King's Landing (Targaryen vs Lannister & Lorch)
Having finally recovered from the devastating Massacre of the Lionstar in 314AB, nine years earlier, House Lannister was ready to attack. In 324AB, House Lannister, and their loyal vassals House Lorch stormed the Targaryen garrison at King's Landing. House Targaryen's next threat were the lions of the Westerlands.
However, in scenes which echoed the battle nine years earlier, House Lannister and House Lorch were defeated in a devastating 52 defeat. Once again, the Lannister forced to fall back from the Crownlands, living to fight another day.
== The Dornish Assault ==
Third Siege of King's Landing (Targaryen vs Dayne & Unsullied)
Having been completely wiped out during the Dragon's Vengeance, being finally finished by the Massacre of the Dragonstar, House Dayne had been in complete disarray for over a half a decade. However, the Dornish wanted vengeance of their own, being lead by Lord Arthur Dayne, or DoMeat. House Dayne had employed the elite Unsullied, led by Torgo Nuhdo, or AvisOni. 
The rebel force would arrive and besiege King's Landing in 325AB, a year after House Lannister, and two years after House Pemford. Optimism and hope flied high for the former crown house. However, despite a closer contest, House Targaryen repelled the invaders 5-3. Although, the Daynish exposed the vulnerabilities of House Targaryen, showing they were beatable. With dozens of rebel armies, it appeared as if there would be many more sieges to come.
== The Sun Sets ==
Battle of Hollard (Velaryon vs Pemford, Teague & Hersy)
Meanwhile, a reformed Riverland Coaltion force made up of Pemford, Teague and Hersy was encroaching upon King's Landing. They were intending to besiege King's Landing after House Dayne. However, their plans were halted by the intercepting House Velaryon. House Pemford's confidence and the majority of their fighting force were shattered during the First Siege of King's Landing. Despite this, many would have still expected the experience powerhouse to defeat the more inexperienced and newly formed House Velaryon. However, Pemford's army had been rushed together and their cohesion with Hersy was weak. Consequently, they were defeated 3-1. 
House Pemford would never recover from this defeat. Their thirty years of being a major influence in the realm were over. The Pemford Quadrumvirate of Lord William, or williterate, Lord Charlie, or charliturus, Lord Tao, or reborntheory, and Lord Hayden, or Northmathr went their separate ways. House Pemford was finished.

Fourth Siege of King's Landing (Targaryen vs Dayne,Celtigar, Sunglass, Royce, Lys, Pemford, Blackwood, Whitehill, Reyne, Lannister, Lorch, Lefford, Blackfyre, Banefort, Gallant Men)
In 325AB, FeriousEagle announced new rules for wars. This rule heavily harmed House Targaryen, as it meant there was no longer a cap on armies involved in battles, with each additional army over three adding an extra soldier. He also announced that a dead crown army will no longer respawn if a house is crown for over 30 days (about four AB years). This rule would have a heavy influence on the outcome of the war, as the entirely of the realm was essential against House Targaryen.
Soon after, King Jaehaerys III Targaryen abdicated the throne in favour of King Baelon I Targaryen.
The grand rebel force reached King's Landing in 326AB. The rebel force consisted of 20 armies, coming from Houses Dayne, Celtigar, Sunglass, Royce, Pemford, Blackwood, Whitehill, Reyne, Lannister, Lorch, Lefford, Blackfyre, Banefort, the free city of Lys, and the mercenary company the Gallant Men. The King's Landing Royal Garrison consisted of just five, being made up of House Targaryen and the City Watch. 
One of House Targaryen's only allies and hand, House Velaryon, recognised Targaryen's dire situation. Lord Daemon Velaryon subsequently stepped down as Hand of the King, declaring his neutrality. The remaining Targaryen allies also chose to abandon their overlords. The new king understood Lord Daemon's position, and merely thanked him for his loyal service up to that point. King Baelon was ready to die in one last defence of his home, King's Landing. He would make the rebellion bleed.
The rebel army, clad in the uniforms of the ancient and extinct House Brightstone, and House Lannister, encroached the inner city swiftly. Meanwhile, the vastly outnumbered Targaryen defenders fell back to behind the Sept, clambering the bulwark behind. House Targaryen had trained in moving troops quickly and efficiently across the narrow ledge, hoping to make a stand against the attackers in a position which suited them. Initially, the rebels were outwitted. However, after nearly an hour of battle, they devised a strategy to assault the Targaryen position. They would have over half their force scale the Sept roof by using each other as a ladder. They would then rally upon the roof, as the remainder of the army would traverse along the narrow edge. When everyone was in position, the rebel force would launch their attack, and overwhelm their opposition. The first round was the longest and closest, with multiple rebels falling off the walls to their death due to inexperience. However, the number advantage was too much as the Targaryen force were surrounded and overwhelmed, albeit whilst killing more than they lost.
The following three rounds occurred in a similar fashion, with the rebels becoming more efficient in their rallying endeavours on the roof and ledge. As the rebels became stronger, the royals weakened. Due to the hours of battle, and increasing experience at assaulting the position, Targaryen fatigue appeared to envelop. Consequently, many of the Targaryen troops fell to their death whilst making the risky traverse to their position of defence, resulting in an even larger rebel number advantage. The remaining Targaryens were simply engulfed and cut down, despite their courageous attempts.
After four rebel round victories, King Baelon knew his cause was lost. Not wanting to fight in the shadows, he chose to lead his army against the foe in one last push. The rebels had not expected the aggression, and their smaller left-flank force was initially outnumbered and beaten. However, in the ensuing chaos, multiple accidental team-kills occurred. King Baelon was mistakenly cut down by his own City Watch Lord Commander Quinton, or QuintonB123321. The rebel response was fast, with the Targaryen force quickly retreating to the sewers, now being led by the former King Maegor III Targaryen, or ActuallyJT. Although, as the Targaryen's retreated through the labyrinth of sewers, they were mercilessly picked off. This was made worse by the sewer exists being camped by the rebels. The rebels beat the dragons by the largest margin yet, winning their fifth round. The reign of the dragon was over.
== Aftermath, Legacy, and Controversy ==
Following the rebel victory, Arthur Dayne ascended to the throne, becoming King Arthur III Dayne, successfully reclaiming the throne in the name of House Dayne. The vast majority of the realm was in jubilation, with the new crown announcing they would take steps to undo the damage House Targaryen did. In the days following, feats were held, the Small Council and laws were reformed, the old Assembly was reintroduced and the new king was crowned in the presence of hundreds.
However, many were dissatisfied with the decision made by administration which all but wrecked House Targaryen's attempts of holding onto power, resulting in them being outnumbered by nearly double. Many saw the rule as biased steps by administration to replace the incumbent crown, with others arguing it was necessary to increase the emphases on alliances and reduce the power of individual houses. The new rule did undoubtedly change the dynamic of the war, as well as future wars, due to a greater emphases being put on alliances and numbers rather than skill. 
With the realm now at peace for the first time since it's rebirth, the new king set his eyes northwards. A new threat was lurking beyond the Wall.
