Out in a forest to the west of the Hyrule boundaries was a single lone figure, riding a well built horse. The figure himself didn't seem all too muscular, though he wore a sword and shield on his back. He was garbed in a green tunic, and he wore leather leggings and boots as well as hidden, golden colored chain mail underneath his tunic. He wore a light-brown leather glove on his left hand, but on his left hand he wore a very thick, black leather glove. He gripped the horse's reigns tightly, and warily glanced about himself, his blond hair flicking around each time his head spun, his green eyes darting about nervously.
Something was just in the air around him. Something malicious and purely evil. And what was strange was that something about this malicious feeling was familiar to him. He didn't quite know why, though. He kept hearing strange whispering upon occasion, and there was no other sound in the forest. Not a single bit of life could be heard about him, which was far more disturbing than anything he had ever come across in the past.
It wasn't long before he could make out the whispering about him as some sort of a magic chanting. The words were foreign to him, as he didn't know a thing about magic. However, the voice chanting the words was cold, and each phrase sent strange shivers of fear down his spine. He hadn't been this afraid ever before, not even against the King of Evil, Ganondorf.
Suddenly, something spooked his horse, a chestnut colored horse with a white mane that he called Epona. She reared suddenly, sending the man flying off and hard onto his back. She then darted off into the mist, and when he sat up to look for her and listen for her, she was gone from sight, as was any noise she had been making beforehand.
The whispering around him got louder and more focused towards one direction. He finally guessed where it was and turned to see the shadow of a heart shaped mask of sorts with spikes coming out of the edges floating towards him. He had remembered seeing something similar to it before, he realized, but where he had seen it...that eluded him. The mask itself was completely dark except for the eyes, which were glowing yellow and fixated on him.
"What are you, evil spirit?!" he asked, drawing his sword and lifting his shield off of his back. He wielded the sword in the hand that had the black glove. The sword itself was a military, double edged long sword that was finely crafted and very sharp. It was also rather easy for him to wield.
The mask cackled and said, "So you don't remember me, boy? You seriously don't remember me since the last time you sealed me away, Link?!"
Link backed up, surprised that this spirit knew who he was. He then gritted his teeth and held his Hylian shield defensively before him. The shield itself was all a metallic gray with the insignia of the Triforce on it. The Triforce were three triangles, one on top and the others below, their tips touching the points on the base of the top one and they were connected by their bases, leaving an empty space that looked like an upside-down triangle.
The mask asked him, "What do you plan to do to me, boy? Do you think that, perhaps, you can fight me in your current state?"
Link said, "I could beat the King of Evil in the past...I can most certainly destroy you!" without warning, he moved his shield to the side and gave a single straight jab towards the mask with his sword pointed towards it. However, his blade stopped inches before hitting the mask, and the mask cackled again.
"Really, now...did you think you could seal me away again with such a puny weapon as this blade? You are a fool to think that you could just so easily destroy Majora's Mask a second time," it said to him and Link shuddered in surprise.
"Majora's Mask?! But...how?! You were sealed away by one of the great heroes of old!" he exclaimed.
The mask cackled yet again before sending a wave of magic at him and blowing him back into a tree. His sword flew from his hand thanks to the impact and he let out a loud grunt as he hit the tree. He stuck to it, the magic holding him there. "I was...but the magic that sealed me away was not strong enough to hold me away forever!" it said to him, getting up in his face.
Link couldn't move at all. The magic had numbed every inch of his body except for his face. He stared defiantly into the eyes of the mask before him, not willing to give up. The mask saw the defiant light in his eyes and cackled once more. "You are nothing but a thorn in my side that I plan to get rid," it said to him.
The bark of the tree gave way suddenly and Link fell back into it with a loud scream. He fell into darkness, which was suddenly lit up by colored images, none of which he really recognized except for one of the numerous recurring symbols. The face of the clock, the hands of which were both at the twelve up in the top. He then felt his descent slow to some degree and he landed in water. He couldn't see anything around him...
Wherever I go, danger follows, so beware those that wish to come with me.
It seems like it is a good start. Short for a chapter though. I find one thing a little disappointing though, this is extremely similar to the start of Majora's Mask. Link, riding alone in a forest, Majora's Mask scares his horse, Epona runs off and link falls, at the end he falls down something that seems endless with tons of symbols. Since your trying to make something that obviously takes place after Majora's Mask, I would suggest give the reader a sense of how old Link is. Judging by what Link says about Ganondorf, I'm guessing it's the adult link from OOT possible 4 or 5 years after which means this takes place 13 or 14 years after Majora's Mask. There's no real age given but since he was raised as a Kokiri who never grow up I'm guessing Kid Link was 12 years old so in this story, Link is in his early 20's. Maybe mention how he is a grown man. Personally, when I read this I imagined someone much younger. These are all opinions, the most important being, try not to use to much more thing's from the original game. Refrences are fine but the way this scene went was very close to a copy of the first scene of MM. Other then that it was good. Everything is very descriptive which is helpful to the reader.
