Overview - 211 AC(You merely adopted the bordergore. I was born in it, molded by it. I didn´t see nice borders until I was already a man)WarsSecond Dance of Dragons
In last years of reign of king Aenar Targaryen, question of succession arose. As all of his male heirs were dead, Great Council was called to King´s Landing. In the end, Aethon Targaryen, descendant of Alysanne Targaryen, was chosen as Aenar´s heir. Yet surprisingly, few years later, Jaenara, daughter of king Aenar and septa, gave birth to a child. Boy, named Aenar, was later brought to court of Aethon´s son, king Valarr. Valarr liked the boy so much he even chose to marry him to his daughter (although he did not legitimize him). Everything was alright while Valarr lived, but as soon as his grandson became king, whispers started to surround Aenar. In the end, he gained support of half of the realm and even multiple other dragonriders when he declared his intent to claim the Iron Throne.
Rebels have superior numbers, as king is not supported by any major house except Baratheons, while rebels have support from multiple Lords Paramount. Meanwhile, loyalists have overall stronger dragons, with another four chained in the Dragonpit, waiting to be tamed (including Dreamfyre „the Dark Fire“, oldest living dragon in the world).Targaryens, dragons and dragonridersLoyalists
Young king of the Seven Kingdoms, Aegon is troubled with old wound from tourney. Despite this, he is willing to lead his armies in battle, not only because he is their king, but also because he rides the most powerful tamed dragon loyalists have, Fenrion.
His sister-wife, Rhaenys, is also dragonrider and rides the most powerful of younger dragons (although phrase „younger dragon“ simply reffers to dragons born after Dance of Dragons), Gorgorkos.
They have three children together, twins Jacaerys and Maegor and younger daughter, Aelora, who is bethrohed to Jacaerys.
Their mother is also still alive, but unfortunately, she has never tamed a dragon in her life. Question is, whether civil war will be good enough reason to descend to Dragonpit and tame a dragon of her own.
Haerys, younger son of king Valarr, also remained loyal, despite his sister´s treachery. He wields sword Dark Sister and also owns dragon egg, which he is yet to give to someone. He rides dragon Aemax (which is actually the oldest of „younger dragons“, but not the biggest).
Daella Targaryen, sister of late king Valarr, is married to lord Qoherys Velaryon, with whom she has three children. She, just like her oldest son, Jaekar, came to King´s Landing as soon as Aenar declared his war, to aid their king. She rides dragon Zalagys, smallest of loyalist dragons.Rebels
Rebellious Targaryens are lead by Aenar Flowers, bastard who wants to become a king, claiming he, as a descendant of king Aenar, is true ruler of Westeros. He rides dragon Sunshine, biggest tamed dragon in the world.
His wife is Daenys Targaryen, daughter of king Valarr, she is disfigured from dragonfire. Yet despite her bad luck, she was able to tame second dragon, Fornaxes.
They have two children together, older Gaemon and younger Baelor. Gaemon is also a dragonrider, as he was able to hatch his egg. Due to his young age (and young age of his dragon), he does not participate in the fighting yet.
Who knows, how long Rhalla Targaryen suspected Valarr was behind death of her brother and husband. While she could not take revenge on Valarr, she can at least destroy his heir in favor of Aenar. She rides Gorthalon, another smaller dragon.
Among surprising Aenar´s allies is Cymella Velaryon, septa who managed to tame dragon Anogaregros and lived in Targaryen court since then. She is the main reason why lady Velaryon, her mother, supports rebels.Neutral
Jaenara Targaryen, mother of Aenar Flowers, is simply too old to contribute to the fighting in any way. And as High Septon chose to stay neutral in this war, he would not even be willing to allow her to be taken to king´s custody.Untamed dragons
Dreamfyre "the Dark Fire" is the only living dragon that lived during Targaryen Civil War. She had many riders over the decades and participated in many battles. She is also impressive in size, being bigger than even Meraxes at the time of her death.
Other dragons have yet to become well known to history, as due to decades of peace, they could only participate in smaller rebellions against Targaryen rule, which were quickly destroyed. All of these dragons are almost the same age, two of them even being children of Dreamfyre herself.Great housesLoyalistsHouse Connington
Given Stormlands in the last years of king Valarr´s rule, they allowed Targaryens to use their resources. Yet due to severe sickness of lord Florian, he is not leading his own armies and instead relies on Targaryens to command troops he provides.RebelsHouse Florent
They have been rulers of Reach for more than 100 years. During all this time, they never rebelled against Targaryen kings and have been in control of their lands for longer than any other great house.House Velaryon of the Vale
Lady Paramount Rhaeys Velaryon was given Vale by Targaryen kings. Yet remaining loyal and thankful for acts of someone´s ancestors is hard when your own daughter joins their enemies.House Stark
Many thought Starks were thing of the past, especially since last of their house, Sybelle Stark, did not have any Stark children. But all of those were forgetting that Karstarks, who ruled the North, were descendants of Starks and the only reason why their name was different was because they chose it that way. Once lady Bethany Karstark became adult, she chose to change this and informed everyone that from now on, members of House Karstark will accept their heritage and will restore House Stark.(Yes, that happened without any notification and I only found out about it while writing this overview. What most likely happened was that Sybelle Stark, who for some reason rules Moat Cailin, was able to use decision to legitimize Karstarks, because she was a ruler. And as she was the last member of her house, she did exactly that. So, House Stark that became unlanded about century ago and was on verge of extinction was benevolent enough to allow House Karstark that ruled the North for that century, to be members of this great house)NeutralHouse Lannister of Lannisport
Less prestigious branch of this house, but also the only remaining since extinction of House Lannister of Casterly Rock. They were given Westerlands after Sarsfields chose to disobey king´s orders and were punished because of that. Yet when time came to aid the king, they remained silent.House Reyne
Trident has always been the least stable of lands in Westeros and this only continued once Targaryens took over. Other kingdoms changed owners, but these created their own lines of Lords Paramount and stability (besides occassional attempts to take original lands of their realms back) continued. In Riverlands, houses changed every few decades. Now, House Reyne rules these lands (and half of Iron Islands), but who knows whether they will keep them.House Volmark
Iron Islands were always more important because of trouble they caused to other kingdoms instead of their own greatness. And when Targaryens came and ended their reaving, they slowly became less and less important. While House Volmark firmly controls these islands, it is not because of their power but simply because Iron Islands can´t even be called Iron Islands anymore. Only Harlaw, Saltcliffe and western two thirds of Great Wyk remain. All other islands are now part of Riverlands, their people actually happy because they can enjoy benefits of being connected to rich lands on the mainland instead of trying to take care of themselves. And just like many times before, Volmarks chose to stay neutral, and just like many times before, nobody really cares.
