Right so it's all here, now.
though the formattings gone wonky.
That just raises more questions! With all their cultural differences and a decreased likelihood that Robert and Ned would be fostered together at the Eyrie, why are they even still friends?
I should point this out to you that yet again, this is just the first ten pages. There's alot of background i've written out on SB that's not been copied over, but the main reason and this i haven't detailed very much on SB either for the fostering is political on the part of Ned's Grandfather who saw it as a way to patch up the relations abit with the Vale, during the man's tenure as Master of Coin for Aegon V, where he met a much younger Arryn. Rickard Stark saw the sense in his old mans idea and amended the idea to send his Spare, not his Heir to the Eyrie, and given the family makeup that determined who Edwyle Stark was, Jon Arryn for all his "traditional misgivings" about Northmen couldn't refuse the the idea. Edwyle Stark, Master of Coin, was the maternal uncle of Aegon V, his sister having married Maekar I in part of a thawing of relations, after a conflict between Artos the Implacable/Bloody Hand and Baelor the Blessed/Befuddled as they were known and infamed.
Daeron, Son of Maekar, was killed by his brother Aerion.
Aerion, the Brightflame, the heretofore only prince ever put on public trial, was subsequently beheaded. and his body burned on a pyre of Wildfire.
Aemon, took the Maesters chain long before these events, so he's still a Maester, by the story time rolls around he's one of 24 maesters serving the Nights Watch. Though he's something of a Primus Inter Pares.
Aegon V ascends the Throne, first Targaryen King since the Dance to favour a house other then Targaryen, the last infamously being Aegon II who favoured his Hightower mother, Aegon V, however is the reason so many of the secret Targ loyalists are willing to hear out the idea of Artos(Jon).
Aegon V, took his colouring from his father and maternal grandmother, but his body was wrought on Northern Bone, as his chronicles like to tell it. In essence he looked like a Stark with Valyrian colouring.
The events of Summerhall plays out in essence similarly to canon, however here there is very little mystery, Aerion, who had been lord of summerhall, had hidden stashes of Wildfire around the place, and during the rites intended to wake the dragons, these went off taking most of the inner circle of the court with the to a fiery tomb.
Jaehaerys II, rules well, but he only rules for six years, and is obssessed with prophecy, leading to the Aerys/Rhaella marriage, and birth of Rhaegar.
Aerys II ascends in 264, events unfold as per canon in many respects.
And to answer your question, better, Robert being a Stormlander and thus not wholly averse to the north as the stormlands have a more Live and let Live approach going on, was thrilled to get to know his northern second cousin, this only got better when it turned out the boy had a puppy with him. Ned of course, was apprehensive about going to the Eyrie but when he found out he'd be fostered together with a boy of equal age, who also was a southern cousin. It got better. Friendships developed, unfortunately Robert was struck with love at first sight when he met Lyanna, and though Rickard saw the sense in a match, none of them thought very long to ask Lyanna what she thought as Robert had swiftly become known as more then a bit free with both the Mead and the Women of negotiable virtue.
Lyanna, ultimately did as she did, because she found out about Mya, and that Robert didn't intend to care for her. Showing that prospects with Robert as far as reliability were concerned, was not good. That Robert later did indeed take care of his bastard children, is in part due to the lessons learned after the rebellion.
That said, Elia was playing a longer game trying to bind Winterfell more tightly to King's Landing and through her to Dorne, so she encouraged Rhaegars infatuation with the younger Stark and to be frank, Elia was not a passive bystander in the romance of this courtship. Had Elia lived, Artos would most likely be married to Tyene or Sarella, with Rhaenys either marrying Renly or one of cousins in the exclaves retying bonds with Maegors line, and Aegon most likely marrying either Daenerys or Margaery, or both.
