there was a certain man
summoned long ago
he was big and strong
in his eyes a yellow glow
some people looked at him
with terror and with fear
but as cambions go he was quite the lovely dear
He was born to bring armageddon, with much destruction and fire
but he fought to not let destiny get him, and did so till he expired
Hell hell hell-a-boy
summoned by as just a boy
there was a man who hated his fate
hell hell hell-a-boy
he hated this destiny noise
He was bound to draw his own enmity.
i don't know how else to say it: jon snow comes from two long lines of reckless magical bullshit and is basically a melting pot of feral royal blood but that's less important than the fact that he was raised by ned stark.
