Here's the prolouge.
Prolouge
Outset Island was a peaceful place.They survived even without contact from other islands. But sometimes it got a bit boring, being stuck on a tiny island in the ocean. Or, at least, that's what Aryll thought. At first, before her brother went on his great adventure, she was happy living on an island with a limited amount of things to do. But after she was held captive in the Forsaken Fortress, she realized that there were many more things to do in the world. After her brother left to explore new oceans, she'd tried to find more exciting things to do on the island, since she was twelve, and her grandma didn't want her sailing off to run straight into monsters.
Neither did Aryll, though she was still bored. She decided to visit Orca, the islands swordsman. . She hoped he could teach her some swordplay. She opened the door and went into the house. At the moment, Orca was spinning around in circles, doing the hurricane spin. Link had generously given him ten Knight's Crests. His body kept spinning around until CLANG-CRASH! Orca's sword had hit the wall and flung off it, and Orca hit the wall too, for good measure.
He got up a little dizzily, and a voice was heard from above. "WOULD YOU BE QUIET? I'M TRYING TO STUDY AND YOUR RACKET IS PREVENTING ME FROM DOING THAT! CAN'T A PERSON SLEEP IN THIS DAM'N PLACE?" Orca rolled his eyes. "Same old brother," he muttered. His brother, Sturgeon, was a brilliant mind at things, though he hated loud noises. Legends said he was once a swordsman himself. He sure didn't act like one now.
Then he noticed Aryll. "Hi, young one. What have you been doing?" Aryll said, "Nothing, really. It's getting to the point where everything is boring. Could you teach me some swordplay?" Orca thought it over. "Well you are twelve, the same as your brother when he first learned to use the sword, so maybe," he mused. "Actually, go ahead! But let's go outside and do it. We don't want Sturgeon getting a headache from screaming his head off." Aryll giggled.
They went outside and found that there was strange sight out. A black symbol glowed in the air. Three upside-down triangles, in the black color. Rose, an animal lover shouted, "It must be Ganon! He's returned!" Orca shook his head. "Ganon couldn't have returned, he's dead. Perhaps its one of his minions." It was at that precise moment that Aryll vanished into thin air.
For some reason, when she woke up, she was still on the island, just a different part. The symbol still glowed in the sky. She realized she was on the bridge to the forest, which had been successfully restored. There was someone else on the bridge, someone familiar.... "Brother?" she said. He was holding the Master Sword. Wait, that couldn't be right. The Master Sword was in Hyrule. "I am not a brother," he said, not turning around. His voice sounded tripled, like if there were two Links talking behind him. "I'm the shadows, darkness, everything you fear." Aryll took a step back. What was wrong with him? He turned around, and his eyes were red. He charged at Aryll. Even if she'd seen what was coming, she wouldn't have been able to avoid the blow. The shadow Master Sword's hilt hit her in the head and Aryll fell off the bridge, into the ocean below.
