>"Do you like it, princess?"
>Celestia eyes the sculpture, scanning its details.
>The artist smiled and waited patiently for her answer.
>This was a fine work of art, yes.
>Celestia stood triumphantly over Nightmare Moon, stabbing the dark pony with a spear.
>Everything about it screamed "praise the sun" and "banish the evil night".
>Truly, to the normal pony's eyes, it was a work of love and appreciation.
>To the normal pony, it was a work that said, "thank you for saving us from this terrible beast".
>Celestia was not a normal pony, though.
>What she saw was a horrid misrepresentation of what happened.
>This sculpture, to her, said, "You banished your sister to the moon. That is equal to killing her."
>To her, it said, "You are at fault."
>To her, it said, "You could have found a better way, but you didn't. Suffer the consequences."
>To her, it said, "Your subjects believe your sister to be a monster. Something wild and dangerous to be put down. They will continue to believe this, no matter what you say."
>Celestia put on a fake smile for the artist, trying her best to shed no tears.
>"It's wonderful, my little pony. I'll have it put in my gallery."
>To the artist and normal ponies, this was nothing more than an honor. A way for the princess to say, "This is a fantastic work of art."
>To Celestia, the non-normal pony, it was just another sick reminder of what she had done.
>It was her punishment.
>And she took it with a smile.
