Ned spent the two days after his audience with the King, sporadically attending the tourney events but most of it in training with the sword or contemplating his outburst about the Wall. These two incidents of ranting about the Wall are uncharacteristic of Ned, he knew himself well enough. So he delved within himself, while in a two hour long meditation session on the fourth day of tourney, Ned had a breakthrough,while he was organizing his thoughts in a meditative state Ned came across a knot of jumbled thoughts, this knot has an alien feel to it, like it wasn't supposed to be there, like an itch once realised was there wanted to be scratched, the knot wanted to be unravelled. So Ned with deliberate care started to unravel it, once it came loose he was assaulted with a deluge of images.
a crown of winter roses
a huge man in a antlered helm raising his war hammer to bring it down on chest of a man wearing helm decorated with three headed dragon
a bed of blood and withered petals of winter roses, a familiar voice begging ' Promise me, Ned'
a newborn white wolf with red eyes silently howling mournfully at the moon, at the dying of the howl leathery wings sprouted of the Wolf's back and white fire spilled forth from it's mouth
a grey wolf brought to it knees and sword of ice about to be brought down on its neck, while a mockingbird trilled joyously in the background
a winter rose growing on the face Wall of Ice
Winterfell burnt and broken
Wall of Ice has cracks in it now and those cracks widened and the Wall came down
in that gap once again the winged wolf stood ,now grown even larger than Frost, snarling silently looking outwards, in the distance countless pinpricks of light of a blue so bright it almost seemed to hurt the eyes to watch, steadily approached
Finally, whispers, in a thousand languages, so loud they drowned out anything else, they repeated insistently, with finality, Winter Comes , Winter Comes , Winter Comes, Winter Comes , Winter Comes.
At that the images and sounds ended and Ned came to himself with gasping ,panting breaths.
' What was that? What in the fucking seven hells was that? '
Those weren't Greendreams Ned knew, he had some before, he forgot most of them before he could write them down, but these images are burned into his mind now, Ned could tell. This was a message, like someone planted it there. Who planted those images? When did they do it? Berek said a Warg has better defenses for their minds than those without magic, has Berek lied? Or is it something else? Berek also said that only a Greenseer is more powerful than a Warg and their powers are vast, but Ned didn't meet anyone with such powers, he would have been able to tell, after his training with Berek he can sense the gift in others, there are some few who has the gift dormant in them whom Ned came across in his time in the South, but never any awakened Wargs, so it wasn't any during last year and a half, only time he wouldn't have identified the images as foreign would be before his training, and the only reason Ned meditated this deep because of his outburst about the Wall. THE WALL! of course it's the fucking Wall, there are no known Greenseers below the Wall and the last known Greenseer is lost beyond the Wall, so possibily a Greenseer who is beyond the Wall planted this message when Ned too went beyond it. This wasn't just a message, its a Warning and Ned has been subconsciously manipulated, urging Ned to strengthen the Wall. Something was coming, it has to do with the Wall. The Others was the first thought, but Ned pushed that down, he needs to know more before jumping to conclusions.
Ned had his mind violated and didn't even know it untill then, it may be to pass along a warning, but still his mind was invaded, that made anger stir in gut and it roared to life in a second. Ned needs to up his training of his gift, Berek always said the Starks were very powerful Wargs, more than Berek himself and that he didn't know all there is to know about the gift. Mind Arts of Warging has more undiscovered and Ned will push himself to discover it. Ned needs to grow more powerful and he will. So that never may another desecrate the sanctity of his own mind, this he swore.
Before any of that Ned needs to meditate again to keep his anger in check and to make sure there aren't more such knots in his mind. He did just that and found none, after having double checking that it was so, Ned remained in meditation. Then he felt two faint buzzes at the edge of his mind, one felt farther away, in the direction of the woods and it was very faint, but another was closer, in the direction of tourney grounds, unlike other Wargs who has the feel of forests and beasts, this one felt like sitting too near a fire. Fire, Targaryens! either the King or the Crown Prince has awakened magic. Fuck, Ned should have been paying better attention, he got this feeling when he was in their presence too, he just dismissed it as nerves.
So the King or the Prince has magic. Not as much as Ned or his family did, and not the magic of First Men, since the feel is different from Seers or Wargs, but magic nonetheless, probably Valyrian magic. Ned needs to find out who has it, the King or the Prince. And he will. Just not today. For now, he needs rest, there are three more days before the tourney ends, he will investigate the King and the Prince tomorrow. Then check out that faint signal in the woods day after that. With that Ned fell asleep.
