Ok, so I was reading the old Zelda manga, the one that ran in Nintendo Power in the early 90's and is based on a Link to the Past (roughly). In said manga, link makes a set of Icarus wings. The guy who teaches Link how to make said wings explains that they're basically magical wings because they were made from the birds the old Knights used to ride way back in the day.
As I understand it, this is a clear reference to Skyward Sword (the ending, especially) which was chronologically the first, or one of the first, Zelda games (as I understand it). How could this manga reference events that weren't chronicled for another 20(ish) years? I don't recall there ever being any mention of the old knights riding majestic birds in any of the games at the time. Was this just a coincidence? What am I missing?
