Gramps who we all know is link from LTTP in LBW and that hes 80 according to rumor guy. so since he was 16 when he defeated ganon and 80 in link between worlds, its a 64 year gap
64 years later
Therefor, forever is 64 years.
But hey, thats just a theory. A GAME THEORY
I like to think that Fi is the narrator. She’s the spirit of the Master Sword, right? After all that bad guy killing, she wants a NAP. She’s also kind of the only person in Hyrule who would remember all of Link’s adventures, being the sword that’s been by his side through every last one of them. It makes sense that she’d be the one to tell the stories.
“And the Master Sword sleeps again… FOREVER” is like “uggghhh… I’m gonna sleep for a WEEK.” or after running a marathon: “that was hell. never again. neverrrrr.” That’s my headcanon anyways. ^_^
thats a pretty good headcanon. phi stated she was essentially ging to die at the end of skyward sword but then again, since she doesnt know how long forever is, she probably only thought she was gonna die
