I was there, you know. Well, not there in the strictest sense, but there through the eyes of the ponies, and dragon, attending. I actually was a distance away in the Everfree forest, doing my little mind-sight spell. Oh, that spell, so many secrets I've learned from it, some dark, some sad, but never happy. Secrets are never happy, for why would they be a secret? So about the service, few words were spoken to those there in favor of a respectful silence. The fillies were more restless than melancholic, such nice kids, they were too young to fully comprehend the impact of what happened, a boon more than anything. They buried her body a little after sunset, something I found quite fitting. After everyone had left I... flew down to the fenced off plot of land, and looked at the stone. Instead of a large, fancy plaque though, I was presented with a gravestone identical to the other five. It said:
Here lies
Twilight Sparkle
The Element of Magic
Simple, fitting, just like her. I'm sure she would've wanted it. I stood there for a while, just looking at the stone. It was then I sensed that a post-death rune had been placed on the back of the stone. Lighting it up, it read:
Tunnel Light:
When I first met you, I thought you were here to hurt me, to drive me to madness. But as I listened to you talk to me, berate me even, something came to me, you gave me something I had been without for years. Hope, and a friend. In these few days we've known each other, you have made me realize that I have been secretly wanting somepony to talk sense into me, somepony that could be plainly, even painfully, honest with me, like my friends of old. And now with your help, I get to see them again. I can not thank you enough for this. One more thing, tell Celestia that I am not angry with her, she shouldn't have to live with any more grief than we all know she already has. Show her this message, comfort her as you have comforted me, that is your special talent after all. This message will disappear after three days, but I hope that it will stay with you both forever.
-Love, Twilight
I could tell you what I did after that, but that would ruin the magic of the moment. I said my final good-byes, and headed off to Canterlot.
It was three days later, and Celestia sat at her throne. Tunnel Light stood at attention in front of her, ready for his verdict. "Tunnel Light," she stated, "for committing actions that led to the passing of Twilight Sparkle, I sentence you... to life. a life of using your special talent to help others pass from this life to the next. You are to continue in this matter until we can find somepony to take your place."
Tunnel Light bowed, "I will serve you dilligently and with integrity" -he looked back up at her-
"until the day I die."
