Reign of Caiden I Stark

"This wasn't what I intended, I was told by the gods." - Caiden I Stark after confronting Arthur III Dayne during his coronation
Caiden I Stark, usually referred as King Caid I was the disputed King of the Andals and first men during the reign of the Dayne Dynasty, around the time before the takeover by Lord Hand Tywin Lannister as King of the Andals and the Whitehill Reign.
Caiden was born in Winterfell, said to have been the Prince who was promised, born amongst salt and smoke, a comet flew above The Sept on the day of his birth: The Reincarnation of Azor Ahai, sent by R'hllor to stand in the darkness. it was said to have never failed a mission and potentially wielded a sword similar to Lightbringer.
Around his early adulthood, Caiden travelled around Westeros, banding an Army of former Targaryen soldiers, Stark Soldiers, and multiple other soldiers, along with the citizens of Westeros, said to be commanded by the great Ser Ibinaldo and Ser Issa, portrayed by Okayissaa. This army would tread far, reaching the city of King's Landing, immediately interrupting the coronation of Arthur III Dayne, portrayed by DoMeat and storming the Keep, said to have occupied it for at least 2 months, initially starting Caid's reign of terror. The Date of his Coronation is unknown, many say it didn't even occur.
Caid was said to have been a vicious and cruel King, with King's Landing been an absolute hellhole at the time, with constant wars, poverty and barely any laws implemented. The Keep was mainly sieged at parts of his reign but managed to hold off multiple stormings of the Keep, with people saying he wielded a sword similar to the Lightbringer on that day. Before he exited King's Landing one day and never came back.
The Prophecy of Caid remains in many as a fruitful story, some say he travelled to Essos, or some even say he's been enlisted in multiple houses under another name. And as the prophecy of Azor Ahai tells, if the return fails, the world falls with them, signifying a near end for Westeros, a new threat.
