re: Crackpot ASOIAF Theories SPOILERS

Crackpot theory:

Ned Stark arrives in Starfall with Jon Snow and "Dawn" (which is actually lightbringer)

He stays there to have Jon nursed by Wylla since he's still an infant and not healthy enough to travel to Winterfell.

While at Starfell, Ned sleeps with Ashara in the process of consoling her over Arthur Dayne's death.

This is how Edric "Ned" Dayne was conceived, Ashara probably threw herself off the cliff or disappeared shortly after his birth.

This would explain Edric's milk mother Wylla as well.
