Explanation of the story [Don't try applying show logic here. This was made prior to the whole \"natural order\" thing they introduced. It doesn't really apply here.]:
The story is... Odd. It's a sick, twisted little creation thought up in my head. I'll paraphrase the lot of it:
Desolate land expands out all around a small village. Not even Unicorn magic can bring life to this dead, empty space. Yet amongst all the dreary scenery live a simple mare with a gift: A gift to give life to the ground around her. Renowned and hated for her gift, she is cast out by many and said to be a witch of sorts.
One day the citizens of this village do what they believe is the right thing: They try and kill the witch. They believed they succeeded until the following day. Carrot Top returned, unscathed and just as serene as ever. Despite their actions, she held no ill will toward the villagers. It was then that the villagers had realized that they had misjudged her.
6 months pass and the story of Carrot Top spreads far and wide. Jealous and enraged by her gift, ponies from far and wide congregate to rid the world of this \"otherwordly\" creature once and for all. However, the villagers step in to protect her, no matter what the cost. Before the conflicts escalates, Carrot Top steps in and offers herself to the enraged ponies.
She is then tied up and burned alive inside her house. Even as her light fades, the welfare of the villagers; her friends, remains her top concern. As the smoke clears, all that is left of Carrot Top and her house is ash and smoldering wood. However, amidst this dark, depressing scene, a small garden flourishes almost instantaneously. Though she is gone, she left her friends a reminder: She will always be there for them.
