(A/N This ending has NOTHING to do with Ending II, got it? Good. I fought writer's block hard for this one, so have fun!)
Luna and Celesita arrived on scene shortly after receiving a frantic letter from Twilight. Luna arrived first, and landed a few feet away from the group of mares. She walked up behind them, to see a sobbing Twilight and Fluttershy. Pinkie's mane was deflated, Rainbow was looking down on the figure with a pained look on her face, and Rarity was completely silent, simply sitting there with a bit of a sad look. Luna walked up behind them.
"He is... Dead?" She asked, as tenderly as she could. she looked over to Twilight, who's horn then glowed, enveloping Alex's form with a similar purple aura. Twilight's teary eyes looked up to her, and she nodded. Luna's face dropped, and a single tear ran down her face, as she turned to her landing sister. Celestia instantly picked up on what happened, and she turned to the group.
"He did all he could. He saved us all. Come now it'll be okay. Where is the dragon?"
Twilight walked over to Celestia and looked up at her with teary eyes. Celestia's question was answered as soon as she looked up past the group, and saw blood, which she assumed that belonged to the dragon, everywhere. Twilight buried her head in Celestia's chest, letting her tears pour out. Why is she so distressed? Has she really taken that much of a liking to this...thing? She shuddered at the thought, before returning her attention to the peaceful looking human.
"We'll give him the funeral he deserves. The funeral of a hero."
Twilight looked up to her mentor, before nodding slightly and turning her attention away.
----------------------------------------------------------
The funeral itself was relatively short. Nopony knew who Alex was, so only the two princess,' and the Elements of Harmony attended. Celestia had a large room under the castle constructed to bury Alex in. His body was quickly put in the vault, and they all quietly watched as his body was moved into the dark room. Celestia sealed the door and nodded to the group. They would all stay in Canterlot with her until they wanted to go home. After watching the whole ordeal, each one of the Elements was a little shaken. Pinkie Pie held a party inside the castle, celebrating Alex's sacrifice for a world he barely knew. This made everypony a little happier, but they were all still shaken from watching someone, who they barely knew, lose their life for them.
One by one, each of them went home. A little sad, but in lifted spirits with the help of a all-too-happy Pinkie Pie. Rarity was the first to go, a bit sad that she never was able to change him 'out of those dreadful clothes.' Fluttershy was the next to go, still sobbing about not being able to help him. Rainbow silently left in the middle of the night, not saying a thing to anyone. Applejack then left, having work for her farm to do. Pinkie Pie then left at the subtle request of Twilight, bouncing happily out the door.
With the rest of them gone, Twilight walked alongside her mentor.
"Celestia... Why did he have to die?"
The question itself caught her off guard. She had no idea what to reply to that. She said one of the only thing that was left to come to mind. Though it probably was not the best answer.
"He did it on his own free will. We don't know why, but he didn't complain...much. He seemed to have a severely disturbed mind, but it did not stray him from doing the right thing. He did it to save us, to save all of my kingdom. And I will never be able to repay him for that."
She looked down to her student, who was getting teary-eyed again. "What troubles you, my faithful student?" She asked, rather blatantly.
Twilight blushed a bit. "H-...He was q-quite interesting. T-their species is something to b-..behold. biped creatures able to do things like that..."
"He was much more than just a regular human being." Luna cut in.
Neither Celestia nor Twilight had noticed Luna enter the room. Out of everypony involved, Luna definitely took it the hardest. She spend all of the days since the funeral in her room, and her sobs could occasionally be heard during the night. The moon was dimmer for the last week, and the stars were not nearly as bright due to this.
"I studied him for two weeks prior to him coming here. He is far from normal, and his mind had been through much. I was surprised to see he did as we asked so easily. It would have seemed he was more intended to kill us rather than assist us."
This sentence cut deep into Celestia's mind. The being her sister had brought here was of no good intentions. He had been evil, though she did think he was bad, she had not expected it to be true after he saved her kingdom. She looked to Luna.
"Sister, what do you mean? Was he not of good intention in the world you pulled him from?"
Luna's face dropped.
"....No."
Celestia's eye's shot wide, along with Twilight's.
"What would you have done had he decided to become hostile against us?!"
Luna smirked.
"Restrain him. He may be strong. He may have slain a dragon, but he would still have been vulnerable to magic restraints."
Celestia sighed, and looked out the window. It was dark, and it was a coming sunrise. The two sisters looked at each other and nodded. They bowed their heads slightly, and their horns began to emit their legendary glow. The sun crested over the ever-so-distant hills.
"...And with that, I bid you a good morning, sister." Luna said, walking towards her room.
Celestia looked down towards her prized student.
"I think it's time you went home, Twilight. Spike is probably missing you, along with all your other friends."
Twilight nodded, and the two went out to her room to pack what few things she had there.
----------------------------------------------------------
With the day winding down, and all of her daily royal duties done, Celestia decided to visit Alex one last time. Though she said that phrase several 'one last time(s)' ago, she still intended on going. After sending her student on her way earlier in the day, she was spent. Her body landed a few feet from the door to the grave, and she looked at it with curiosity.
"My my... What is this?"
Upon closer inspection, there was a long wall glowing dark-blue text lining his grave door. Celestia read it aloud, in a quiet, peaceful voice.
"Down in these corridors
Lies one of many unsung heroes
Though his legacy is lost in time
His legacy is not lost in our memories
Though few knew him
Many more were affected.
Even without them knowing
Let alone saying thanks
He lies here
Alone
In his final resting place.
If it were not for him
This world would have ended
And with this message
I give my blessing.
May you live graciously in the afterlife, Alex.
-Luna
And next to the long wall was one of Luna's pendants, lodged and enchanted into the wall, signifying her blessing for eons to come.
With a small smile, and a single tear going down her face, Celestia backed away from the door, and flying back up to her royal palace.
----------------------------------------------------------
After writing her final poem, Luna teleported into the tomb, bypassing Celestia's magic with her own. She sat next to Alex's coffin, and pressed her horn lightly to it, causing the whole tomb to be engulfed in a bright blue light. She smiled, and the tears began to flow.
"I wish I could have saved you sooner, Alex. If I had known you could have died, I would have never brought you here."
She levitated the real pendant off of her chest, and opened the coffin. She place it gingerly between Alex's hand, and closed the coffin. She sighed audibly, then teleported out. The fake pendant on the door will glow until the end of time, and the pendant that Alex has will ensure his soul is safely transferred to whatever afterlife that exists.
Luna found herself in her room. She walked over to her bed, and looked underneath. She slid out a small human shoe box. Opening it, she lifted out a picture of her and Alex. Though he never knew it. Alex was accompanied by Luna the entire time of his infection. She had transformed herself to appear like his sister, and gave him as much help as he could in that world. She preformed a obviously very convincing facade that she had no idea who Alex really was when he arrived.
She set the picture on her night stand, and laid on the bed. Looking out the window, it was time for the sun to rise. her horn glowed slightly, bringing the moon down out of the horizon. She smiled, and rested her head on her pillow, drifting off to a quiet sleep.
----------------------------------------------------------
Seven years later...
Luna quickly brought up the moon, not wanting to miss her yearly night she spend at Alex's grave. She quickly flew under the castle, and walked right through the grave's door. he came upon the glowing coffin, and she sat next to it. A tear came down her cheek, as it always did on this night. She put her head on the coffin, and sighed lightly. She could spend the rest of this night in silence, hoping to keep Alex's memories alive. She felt herself forgetting what he looked like every year. She decided it was time to refresh her memory. She lifted up the roof of the coffin, and what she saw astounded her.
Alex was still in perfect condition. After 7 whole years, his body had not even slightly decayed. He still had color to his cheeks, and a glow to him. the pendant was still stuck between his hands.
I guess that is the one effect 'Tia never told me about...
She closed the coffin, and laid lightly next to it. Here should would spend the whole night, and most likely most of the next day, in silence. She closed her eyes, and quietly thanked Alex again for everything he did. For the next thousand years, he would be remembered by her, thought not by everyday ponies, but by her. She quietly reached into the coffin, and removed the pendant. She smashed it with her hoof, and it burst into powder, she used her magic to spread it entirely over him. She watched as he began to glow brightly, then it faded. His chest rose and fell once, letting out his final eternal breath, releasing his soul completely. She watched as the color drained from his body, and he went fully limp. She began to cry uncontrollably, and stuck her head into her hooves. In truth, in the time she spend with Alex, she secretly grew a liking to him. He was her one chance left at romance, and she had let him die. She never knew if he would fancy her back at all, but she had high hopes.
"I'm so sorry, my prince... I'm so sorry..."
(A/N I know the whole 'Luna=Sister' thing really doesn't tie into Prototype itself as a game, but I like it like this. Deal with it.)That's all folks! Thanks for coming along this whole ride!
