The War of the Dragonstar

The War of the Dragonstar was a major military conflict that occurred in the Crownlands and the Reach between rebels House Targaryen, and the crown House Dayne, and also House Bulwer and House Hightower . The rebellion occurred from 304AB-308AB. The conflict led to the defunction and change in establishment of House Targaryen, and solidified House Dayne's position and dynasty.
== Prelude ==
The recent War of Eight Kings was indecisively won by House Dayne, despite losing to House Targaryen during the Battering by Summerhall. This was as Lord Tywin V Lannister, or SSWEEEEjr, defeated House Targaryen in the Battle of King's Landing in 302AB, afterwards choosing to grant the throne to King Vorian II Dayne, or HiddenBladed.
== The Dragon Declares ==
As a result of outcome of the aforementioned war, Lord Rhaegar was furious.
During 304AB this outrage became known, with Lord Rhaegar distributing a message to all lords of the realm. The message was long and brutal, ripping into House Dayne and House Lannister. Part of the message read "House Targaryen does not recognize House Dayne as the Crown House"..."House Targaryen declares open rebellion on the Crown. Dragons do not bow to cowards."
The proclamation was not surprising. With an impending Targaryen rebellion almost guaranteed, many lords had already planned for the conflict, with the majority of houses publicly declaring their support, with several neutrals.
== Battles of Bulltower ==
First Battle of Uplands & Second Battle of Uplands (Hightower vs Bulwer)
With House Dayne preoccupied with their defence of King's Landing, Dorne was open. House Bulwer had pledged their loyalty to the Dragons, with Lord Rhaegar instructing Lord Bulwer, or Zaenac, to attack Dorne and Dayne's seat of Starfall in the hope of distracting them. 
However, the crown loyalist House Hightower's seat of Oldtown was only one tile to the east of Bulwer's Blackcrown . House Bulwer would therefore have to attack Lord Leyton Hightower, or QuintonB123321, if they wished to take Starfall.
This situation led to the First and Second Battles of Uplands by Oldtown, which were both convincingly won by House Hightower, haltering House Targaryen's plan of seizing Starfall, and wiping Bulwer off the map.
As a result of Lord Leyton's loyalty and success, he was named Warden of the South.
== The Great Siege ==
Siege of King's Landing (Dayne, City Watch and Kingsguard vs Targaryen)
With the war declared almost directly after the War of Eight Kings in 304AB, very little fighting took place until 308AB. This was as the map was only recently released, and the travel time between Dragonstone and King's Landing was so long.
However, when the Targaryen fleet of three seperate navy groups carrying three armies arrived at King's Landing, which was defended by thee Dayne armies, as well as the City Watch and Kingsguard, a great and bloody but one sided siege broke out.
The Targaryen forces stormed the walls with overwhelming success, with the Dayne force choosing to fall back and hold them off at the staircase connecting the upper parts of the city to the courtyard. With this staircase being a horrifically narrow and steep bottleneck the battle seemed a stalemate, with both armies facing each other off from their respective positions.
After several hours of fighting and stalemate, including single combat watched by both armies between the victor Prince Arthur Dayne, or JusticeBladed, and Targaryen's Kingguard Lord Commander Lewyn Martell, or Sanguiniam, the Dayne's determination and dedication prevailed. This was despite a late charge by House Targaryen, which somewhat broke Dayne's robust formation. House Dayne won the siege 5-1.
== Aftermath and Legacy ==
As all of Targaryen's armies were involved in the siege, their entire fighting force was wiped out. Furthermore, the Second Sons had captured their stronghold and seat of Dragonstone, meaning they where without both armies and territory. Lord Rhaegar pledged to leave the realm should he lose; a pledge which he kept. House Targaryen became defunct, with a change in establishment and new Targaryen line emerging.
The war was also important in establishing House Dayne as the undisputed Kings of the Seven Kingdoms, with many before resenting them due to their unconvincing initial ascension.
The siege was up until that point, the largest amount of armies participating in a single conflict, surpassed only by the United Realm Army's Assault on King's Landing almost 20 years later in 326AB.
Shortly after the war, King Vorian II Dayne abdicated in favour of his son, the previously mentioned Prince Arthur Dayne, who became King Arthur II Dayne, King of the Seven Kingdoms.
Four years later in 312AB, a reformed and new House Targaryen returned, inciting the Dragon's Vengeance.
