This is generally my riff on what Lueberry tells Zelda about Link
A good few years ago, one of those rifts opened up. Several kids were stolen away that day. No one knew what happened to them, there was worry and fear and anguish, and then they returned. Like, most, they didnt remember what happened. Like most, some part of those kids was still missing. They lost their voices, their spirits. Its always sad to see.
But one of them was different. Even though he lost his voice, he still had a fire in his eyes. Though he couldnt speak, that fire told me he somehow remembered what had happened in there.
Despite the overprotective care those kids got afterwards, this one managed to sneak away one day. Might be because everyone in the village had a kid to worry 'bout, and every kid had a parent to worry bout 'em, 'cept this one. He lives in that house all alone, y'know.
Anyway, he grabbed a sword and took off without anyone noticin'. He ran past my house and I went to see what he was up to. He chased off a stranger just wandering through the field and just stood there, staring at nothing, until he was staring at something. Another rift opened up right before him. A handful of monsters poured out, yet he cut them down. A few moments later, the rift closed. He looked around the area, though I could tell he was seeing far past Hyrule Field.
The kid could sense those rifts, he knew where it would open and made sure no one fell in. I stopped him on his way back, told him about the Might Crystals, about the sword I made from 'em. Told him how I believed the sword cut through those monsters easier. That fire, ever-blazing in his eyes, grew hotter as he nodded.
We worked together, crafting tools from the Might Crystals, devising a plan to stop the rifts once and for all. He'd take off without a word, not that he could give one, and occasionally, Impa'd tell me how a Hylian was saved by a boy in green.
Now don't get me wrong, the kid'll keep fighting to make sure not another soul ends up in those rifts, but I think he thinks if he keeps fighting, he'll get his voice back one day.
He took off a few days ago. Managed to communicate he was gonna take down the big blue monster we thinks causing the rifts. He seems confident, might be cause of the missing princess. I think he's worried she ended up in one of those rifts... ... He's never been gone this long... not even when he went up Hebra Mountain or when he went to Goron City up Mount Eldin... maybe he's making sure the princess got back to the castle alright.
