Well, where to begin?
I would suppose I should start by introducing myself to this blank book Lady Zelda insisted I write... My name is Demon Lord Ghirahim, though, I go by Ghirahim now days...
I bet you are wondering how I came to be acquainted in the right way with Lady Zelda. Well, I would guess it started when Demise was revived...

"Welcome back, master," I said with a bow. Finally, after all my pains, all my striving, my headaches, my mission was complete. Demise was revived, and by the look on his face, he was pleased. Though, I don't think he heard me...
"Master?" Demise looked at me, giving one of his pleased smiles.

"It is good to be back," He said, lowering his hand. "I believe you have done me well-" His eyes landed on the Sky-child, who was staring back, terror in his eyes. "Who is this," Demise snarled, pointing at him. I ducked my head as I replied.

"That is Hylia's chosen hero, Master. He is known as Link-"

"Why did you let him live," Demise interrupted, turning to glare at me. I gulped.
"My Master, what do you mean-"

"I mean in the Sky View Temple, and in the Fire Sanctuary," Demise growled. "You let him live twice, thrice even! I won't even mention the pathetic monsters you summoned to kill him." I felt my anger rise, I tried to kill him, but he was more stubborn then a Goron. And believe me, they are quite stubborn!

"Master, I have no excuse for him living still-"

"Then I have no use of you," He interrupted again. My mouth fell open.

"Master, what do you mean-"
"I mean that you can't defeat a simple Hylian, Demon!" His fiery mane glowed brighter as his rage sparked. I recall shrinking back from the heat. "You have grown weak, and have no more use to me." He turned to speak with the Sky Child, but stopped mid-turn. Demise smiled mockingly at me as he added, "Have you grown as dumb as they?" He gestured to The Sky Child, who stiffened. My anger rose still, how dare he insult me! What I did next I do regret. I see now that it had to happen, although it does not mean I am satisfied with it.
"Master, I assure you, I am an intelligent being, and might I remind you of all I have done? You wouldn't even be here without me!" Demise turned to me, rage on his face, I made the unfortunate act of wincing. Because this is a private book, I will make the point of admitting that I was afraid. As all beings should be when they face him! His gaze deepened.

"You are just like them, Demon," He said, his voice calm and quiet, striking fear into my heart, and yes, I do have one! "You fear me, like you did before I found you..." He lifted up his hand and waved it in a way like he was dismissing me. My legs went rigid as magic hit me, the force was enough to knock me back. I tried to scrabble to keep myself upright, but Demise pushed just a little more and I fell on my back, my arms held out straight.

"What are you doing?!"

"What I should have done long ago..." I felt the rest of my form go rigid as a red magic engulfed me, it then lifted me into the air. A ball of light emanated from the red Diamond on my chest, that's when the pain started... From the ball of light, a hilt of a sword came, I watched in horror as more of a sword sprouted from my chest. I must say that I yelled in pain, though it sounded like Laughter. The sword, once clear from my chest, flew to Demise's hand, his eyes narrowed up at me.

"To me," He said, holding the blade of the sword out to me. The Red light intensified around me, I was in too much pain to remember what happened next, though I believe it might be for the best.

I grow tired as I write this, perhaps it is the pain of memory, but I will write on, seeing as it isn't a page yet and Lady Zelda expressed it had to be one page long before I retire for the evening. When I was able to see through the pain, I was in a clouded area, water lay under me. I still in my true form, no not the sword, the metal creature of black and white. I was able to move, so I assumed an upright position. The Sky Child was fighting with Demise, each time the Master Sword struck Demise's sword, pain echoed through me.

"Ghirahim," An echoed voice chimed behind me. I turned to see Fi standing behind me, her face expressionless as always. I would guess that you don't understand, so I will explain. When the master of a sword spirit summons the spirit, it seems to appear from a jewel somewhere on the hilt. That is not the case.
The Sword Spirit watches, invisible and mist like, taking up a solid form when their master calls. Now you're wondering why I'm always solid. I guess I'll have to explain that later, when I find out for myself. "You are different then when we last met like this," She chimed again, floating towards me. I couldn't help but snort.

"Last we met was not an hour ago," I said, pulling my knees to my chest, wincing as that Sky-Child ran down Demise's blade. "How could I have changed?"

"You are unsure of what you know," Fi said, standing next to me. "Your Master has rejected you, and if my calculations are correct, you are emotionally unstable." Once more, I snorted.

"When am I not?"

"You weren't when the Sages made you," She chimed, just as I finished speaking. That left me no words to say.
"What," Was the only thing that I could say.

"The Seven Sages made you, just as they made me." I stood up and made my way to slap her, she moved out of the way so I slapped empty air. The Seven Sages made Fi, under Hylia's directions, but I knew one thing at that point, Demise made me, so I made that statement to Fi, best I could.
"THAT BLASTED GODDESS DID NOT MAKE ME," I shouted. "SHE'S NOTHING MORE THEN A DITSY BLONDE, INCAPABLE TO EVEN PROTECT HERSELF!" Fi remained emotionless as always, but I knew I struck a nerve.

"Her Grace is not a 'ditsy blonde', and she is able to do many things. I believe your calculations are correct, however. She would not be able to create a monster such as you-"

"I am a demon, Fi, not a monster," I corrected.
"You are a sword spirit," Fi corrected. My anger rose again, past the boiling point. "You have never been a demon." The sky turned darker then my mood as Demise summoned Lightning to his sword, Energy flooded through me, but left almost as quick as it had come, leaving me weaker then I had been. The Sky Child, Blast him, figured out the trick and blasted Demise with lightning, pain surged through me.
"BLAST THEM ALL," I shouted, writhing on the ground from the shock, pardon the pun. Fi floated next to me, not helping.
"You didn't deserve that," She said as I finally stopped surging with pain, pardon this pun too. I glared at her, slowly standing and clutching the diamond on my chest.
"Of course I didn't!" I could barely breathe, the only thing I could feel was pain, not the water under my feet, or the wind across my face, just pain. The Sky child caught a blast of lightning with the Master Sword's blade, Fi didn't even flinch. I glared a little harder at her.
"Why didn't you flinch," I growled, grabbing my middle and bending over to heave as Demise was struck again.
"The Demon King wants you to feel the pain, he is transferring his own into you. 99% indicates it's reason is revenge-"
"I DON'T WANT YOUR PERCENTAGES FI," I yelled at her. "I WANT IT TO END!" Almost as if the Goddesses were playing some cruel trick on me, The Sky Child landed a fatal blow on Demise, pain engulfed me. I barely remember what happened, Demise said something about a curse that would follow the Sky Child and his descendants for eternity, but I was fading fast, maybe it was because the sword I was housed in had shattered in purple smoke. I started to fall through the watery ground, but I was in so much pain, I couldn't move. Fi knelt next to me and stared at me, blank as ever.
"You want it to end," She asked. I blinked, trying to say something, but I couldn't. "Then return to who you were, Ghirahim. Return to what you were before the war..." And I knew nothing more.

My hand hurts from writing this, and tears dot the page. I still have more to write before you are caught up to the present day, but if I write anything more, I fear that my hand will shake enough to rend my writing unreadable. Dear book, I will explain one simple thing to you. I did not die, I lived, for what purpose I know not, but I know Fi and the Goddess Hylia had something to do with it. That is why Lady Zelda has me writing this, so that I may conduct my investigations and not let my anger, or my sorrows, interfere with my investigation. I believe I will shut the book, so that I may tend to my headache before it grows worse.

Your Writer,
Ghirahim
