@chaouenmadrid you asked about evidence that Euron is Bloodraven’s bad seed:
Bloodraven’s strongly associated with birds and eyes, and then we get Euron calling himself “Crow’s Eye,” using a banner showing birds crowning an eye (an eerily perfect representation of the three-eyed crow opening third eyes), and above all, sharing this:
“When I was a boy, I dreamt that I could fly. When I woke, I couldn’t…or so the maester said. But what if he lied?”
That’s an exact parallel to Bran’s introduction to Bloodraven and the third eye, even down to the discouragement of the maester. So I think Euron was one of Bloodraven’s earlier choices for the savior role that Bran later came to play; Bloodraven was impressed by Euron’s raw talent enough to tell himself he could work around the whole “Euron being the Antichrist” thing. When I say Euron’s an interloper-antagonist hijacking the story, consider that at one point, he was auditioning to be the story’s protagonist. And then, of course, he did what he always does: absorb all the power and ignore the attendant ideological structure.
Euron’s entire story and its themes spring from this moment in his youth. No matter how evil he ever got, he’d never have become the would-be god of a global graveyard, an existential threat to the basic metaphysical order of things, without Bloodraven showing him the path. He followed it to Valyria, and he’s going to follow it into Doom. Not for nothing does GRRM have Moqorro share this vision of Euron’s true nature and endgame…
“A tall and twisted thing with one black eye and ten long arms, sailing on a sea of blood.”
…as he’s passing by Valyria’s Doom.
As well as providing the perfect context and backstory (he’s Evil Bran) for Euron’s occult trappings, this just fits too perfectly with Bloodraven’s story. As a politician, the failure that birthed all the rest was focusing so exclusively on the Blackfyres that he let other threats metastatize…including, hey, the Greyjoys. And in his second life, though fighting the true enemy now, Bloodraven made the same mistake: he considered the Others such an urgent and overwhelming threat that enabling Euron, quite clearly already the Omen kid crossed with Doctor Doom, would be worth it.
And here’s the great terrible beautiful irony of it all. By thinking that nothing else mattered if Euron could help fight the Others, Bloodraven ended up ensuring that the Others would invade Westeros at large, because his rogue pupil is going to blow the Horn of Joramun, bring down the Wall, and let the monsters in.
There’s also this line:
Euron turned to face him, his bruised blue lips curled in a half smile. “Perhaps we can fly. All of us. How will we ever know unless we leap from some tall tower?” The wind came gusting through the window and stirred his sable cloak. There was something obscene and disturbing about his nakedness. “No man ever truly knows what he can do unless he dares to leap.”
The associations between dreaming of flying and third eyes and crows are already there, but the association between flying and leaping or falling from a tall tower is way too close to (and too specific to) Bran’s dream from Bran III of AGOT to be a coincidence.
