I don't really remember the books in much detail (I need to reread) but could you please tell me which book talks about Bloodraven, Shiera Seastar and etc?
This is a tricky question for me, because the first I really recall reading about them is on westeros.org, GRRM’s Targaryen descriptions for the artist Amoka. (Bloodraven; Shiera. Note many historical Targs were described for that artist in far more detail than they ever were in the books.) I know that Bloodraven was definitely mentioned in AFFC, and both of them in ADWD, but let’s see if there’s anything anywhere else:
Maester Aemon preferred to spend his days on deck as well, huddled beneath a pile of furs and gazing out across the water. “What is he looking at?” Dareon wondered one day. “For him it’s as dark up here as it is down in the cabin.” The old man heard him. Though Aemon’s eyes had dimmed and gone dark, there was nothing wrong with his ears. “I was not born blind,” he reminded them. “When last I passed this way, I saw every rock and tree and whitecap, and watched the grey gulls flying in our wake. I was five-and-thirty and had been a maester of the chain for sixteen years. Egg wanted me to help him rule, but I knew my place was here. He sent me north aboard the Golden Dragon, and insisted that his friend Ser Duncan see me safe to Eastwatch. No recruit had arrived at the Wall with so much pomp since Nymeria sent the Watch six kings in golden fetters. Egg emptied out the dungeons too, so I would not need to say my vows alone. My honor guard, he called them. One was no less a man than Brynden Rivers. Later he was chosen lord commander.” “Bloodraven?” said Dareon. “I know a song about him. ‘A Thousand Eyes, and One,’ it’s called. But I thought he lived a hundred years ago.” “We all did. Once I was as young as you.”
—AFFC, Samwell II
[In the Winterfell crypts, looking at statues of the old Stark lords]:
Lord Beron Stark, who made common cause with Casterly Rock to war against Dagon Greyjoy, Lord of Pyke, in the days when the Seven Kingdoms were ruled in all but name by the bastard sorcerer men called Bloodraven.
—ADWD, The Turncloak (Theon V)
Bittersteel and Bloodraven both loved Shiera Seastar, and the Seven Kingdoms bled.
—ADWD, The Kingbreaker (Barristan III)
Looks like AFFC and ADWD is it for the main books, then. Although there is quite a bit more description of them (well, Bloodraven, at least) in the Dunk and Egg stories:
The realm was full of lawless men these days. The drought showed no signs of ending, and smallfolk by the thousands had taken to the roads, looking for someplace where the rains still fell. Lord Bloodraven had commanded them to return to their own lands and lords, but few obeyed. Many blamed Bloodraven and King Aerys for the drought. It was a judgment from the gods, they said, for the kinslayer is accursed. If they were wise, though, they did not say it loudly. How many eyes does Lord Bloodraven have? ran the riddle Egg had heard in Oldtown. A thousand eyes, and one. Six years ago in King’s Landing, Dunk had seen him with his own two eyes, as he rode a pale horse up the Street of Steel with fifty Raven’s Teeth behind him. That was before King Aerys had ascended to the Iron Throne and made him the Hand, but even so he cut a striking figure, garbed in smoke and scarlet with Dark Sister on his hip. His pallid skin and bone-white hair made him look a living corpse. Across his cheek and chin spread a wine-stain birthmark that was supposed to resemble a red raven, though Dunk only saw an odd-shaped blotch of discolored skin. He stared so hard that Bloodraven felt it. The king’s sorcerer had turned to study him as he went by. He had one eye, and that one red. The other was an empty socket, the gift Bittersteel had given him upon the Redgrass Field. Yet it seemed to Dunk that both eyes had looked right through his skin, down to his very soul.

“You’ve known queens and princesses. Did they dance with demons and practice the black arts?” “Lady Shiera does. Lord Bloodraven’s paramour. She bathes in blood to keep her beauty.”
— The Sworn Sword
“The Blackwoods will never stomach the Brute of Bracken as a neighbor. It will mean war.” Dunk knew about the ancient enmity between the Blackwoods and the Brackens. “Won’t their liege lord force a peace?” “Alas,” said Septon Sefton, “Lord Tully is a boy of eight, surrounded by women. Riverrun will do little, and King Aerys will do less. Unless some maester writes a book about it, the whole matter may escape his royal notice. Lord Rivers is not like to let any Brackens in to see him. Pray recall, our Hand was born half Blackwood. If he acts at all, it will be only to help his cousins bring the Brute to bay. The Mother marked Lord Rivers on the day that he was born, and Bittersteel marked him once again upon the Redgrass Field.” Dunk knew he meant Bloodraven. Brynden Rivers was the Hand’s true name. His mother had been a Blackwood, his father King Aegon the Fourth.
— The Sworn Sword
“Lord Bloodraven’s not even a real lord, that’s just some stupid courtesy. He’s a sorcerer, and baseborn besides.” “Bastard born, not baseborn.” Bloodraven might not be a real lord, but he was noble on both sides. His mother had been one of the many mistresses of King Aegon the Unworthy. Aegon’s bastards had been the bane of the Seven Kingdoms ever since the old king died. He had legitimized the lot upon his deathbed; not only the Great Bastards like Bloodraven, Bittersteel, and Daemon Blackfyre, whose mothers had been ladies, but even the lesser ones he’d fathered on whores and tavern wenches, merchant’s daughters, mummer’s maidens, and every pretty peasant girl who chanced to catch his eye. Fire and Blood were the words of House Targaryen, but Dunk once heard Ser Arlan say that Aegon’s should have been Wash Her and Bring Her to My Bed.
— The Sworn Sword (note multiple other mentions of Bloodraven within this story, including a description of the Battle of the Redgrass Field)
How many eyes does Lord Bloodraven have? the riddle ran. A thousand eyes, and one. Some claimed the King’s Hand was a student of the dark arts who could change his face, put on the likeness of a one-eyed dog, even turn into a mist. Packs of gaunt gray wolves hunted down his foes, men said, and carrion crows spied for him and whispered secrets in his ear. Most of the tales were only tales, Dunk did not doubt, but no one could doubt that Bloodraven had informers everywhere. He had seen the man once with his own two eyes, back in King’s Landing. White as bone were the skin and hair of Brynden Rivers, and his eye—he had only the one, the other having been lost to his half brother Bittersteel on the Redgrass Field—was red as blood. On cheek and neck he bore the winestain birthmark that had given him his name.
— The Mystery Knight
He was older than Dunk remembered him, with a lined hard face, but his skin was still as pale as bone, and his cheek and neck still bore the ugly winestain birthmark that some people thought looked like a raven. His boots were black, his tunic scarlet. Over it he wore a cloak the color of smoke, fastened with a brooch in the shape of an iron hand. His hair fell to his shoulders, long and white and straight, brushed forward so as to conceal his missing eye, the one that Bittersteel had plucked from him on the Redgrass Field. The eye that remained was very red. How many eyes has Bloodraven? A thousand eyes, and one.
— The Mystery Knight (and again, many other mentions within this story)
Oh, and under the cut are the descriptions of the last greenseer in ADWD’s Bran chapters, so you can see who he is for sure.
This was totally not where I had initially thought where this piece would go. Though that is the part I tend enjoy when creating art. Sometimes you complete your vision and sometimes what you end with is better than your initial idea.
And perhaps this is the theme I will use for the rest of the GOT stuff I am now wanting to do. Really partial to the motif border in the opening credits, so we will see what I end up playing around with.
