I think this is really interesting and spoilery, but have not seen anyone write about it.
"“Sure,” River said. “But I taught him. And he’s just about gotten to the end of his path.” He looked uncomfortable. “Lot of the wizards who matter are near the end. Hanging on hard.” I tilted my head at him. “Why?” “Not the right person, time, or place to tell you, starborn.” I pursed my lips. “Six hundred and sixty-six years,” I said experimentally. River’s craggy brows rose, itself a feat of superhuman strength. “Huh,” he said. “You learned some things.” “I learned that,” I said. “We pretty close to that time,” he said. “Kinda promised not to tell you anything. Sucks. Necessary. But if I was you, I’d think hard about taking my offer.”

So does this mean that Listens to Wind is a Starborn? Who else is exactly 666 years older than Harry?
Uh, I did not understand that, TrueMonk. Only that:
every 666 years, something really important happens, and many wizards die in the process but before that, they hang on hard. LTW is old, his time is ending, that is all.
In the forums it has been suggested that Merlin (the original one) was a starborn. After PT I am wondering if Mab was one herself. Also I was pretty sure we had a WoJ that Elaine was an starborn, but if the "window" to have an starborn was so short (a few hours) I don't believe that is the case. So perhaps he changed his mind
