Before you rule this theory out as insane, just read through and you’ll be pleasantly surprised. In fact, it all makes perfect sense.
Game of Thrones is one of the most popular and talked about shows on Television today. It has garnered a cult following, with good reason, and fan theories are at every corner. And this is another one (yes, I know it’s not a fact, but I do love the show).
So yes. My theory is that the Mad King, King Aerys II Targaryen, wasn’t mad at all, but was hearing the voice of Bloodraven. Not only was he not mad, but he wasn’t killed by Ser Jaime Lannister, but by Bran Stark, in a mistaken and ill informed attempt to do what was right. Let’s break this down.
1. King Aerys II Targaryen wasn’t mad
We picked up in Westeros quite a few years after King Roberts Rebellion. While the catalyst for the rebellion was Prince Rhaegar’s abduction, rape and murder of Robert Baratheon’s betrothed, Lyanna Stark, sister of Eddard Stark. The most prevailing theory is that she wasn’t abducted at all, but ran away, got pregnant and bore a son. That son is none other than Jon Snow. This is known as the R+L=J theory. But the houses of Westeros wouldn’t have risen up against the throne over an abduction. But throw in some madness, and it gave them a reason to join houses Baratheon and Stark.
King Aerys is often described as being mad. He was said to have constantly heard voices and been cruel beyond words towards his subjects. How much of this cruelty can be subjected to the history of the victor isn’t known, but there’s no doubt that he was cruel. But he wasn’t insane.
In season 6 of Game of Thrones we see Bloodraven and Bran Stark visit the Tower of Joy where a young Ned Stark fights to free his captive sister. After the short battle Bran calls for his father while Bloodraven tries to stop him, and Ned stops, as if he heard something. Bran is convinced Ned heard him, but Bloodraven rules it out.
