Aerys I Targaryen of Whitefyre

Aerys I Targaryen of Whitefyre was a member of House Targaryen-Whitefyre, cadet branch of House Targaryen and the First son of Maegor Targaryen and Vaella Targaryen founders of the Whitefyre House. Aerys was also the first King of the Kingdom of the Three Islands, when he unofficially started the colonization and settlement of the Islands in an attempt to rule a dominion of his own right after his family was banished and exile from Westeros following Robert's rebellion.

He was born in Westeros, in Dragonstone in the year 247 A.C, but his family soon relocated to Kings Landing where they lived in a modest house till the year 270 A.C at age 23, when his family moved back to Dragonstone after the increasing madness of Aerys I Targaryen scared them away. At the start of Robert's Rebellion, in 282, he moved with his family to Lys. He was 35 years old. They were taken in House Zyran household of Rockbone, due to the marriage (and alliance) between him and Naerys Zyran, daughter of the Head of house Zyran.

He lived in Lys for most of the rest of his life in exile, and spent most of his years trying to gather as much money as possible to colonize the three islands named as the Targaryen Islands. He worked in service of different mercenary companies gaining battle experience and expertise. Some of his time in Essos was mostly fighting as a mercenary and accumulating wealth to allegedly buy several ships. He thus gather money, men and ships and became the first to settled in the Targaryen Islands, wishing to create his own Kingdom.

Aerys visited the Islands and created several posts there, naming himself "King of the Three Islands". However, as soon as he learnt about the rebellion taking place in Westeros against the Targaryens by Robert, it was too late and the King had already been deposed as Robert had been crowned.

When Robert depose the King Aerys I Targaryen, Maegor and Vaella renounce to their claim to the Iron Throne once again at their very old age (and probably to avoid being killed by Robert) from their distant residence in Lys. Aerys did not take well the fact that his own claim had been put to the side and not even considered and even though Robert granted him a pardon, it has been speculated that he was to be found in Lys and executed. Lucky for him, he had already sailed to the Three Targaryen Islands. Aerys always saw Robert as an usurper and claim himself to be the rightful heir to the iron throne.

He tried then to gather troops and an army for a counter offensive, but such plans never came to terms. In spite of his experience in warfare as a mercenary, few dare to join him and his seemingly strange cause. However, he still tried with the few troops that he managed to gather, but he was soon defeated and executed in the known "Whitefyre Rebellion". He was killed in 290 A.C at the age of 43.
