The Corruption of Harmony
Slaneesh was pleased with himself. She has single handily found this new dimension, right behind the other gods backs. Oh, how he will rub it in the others faces when he has every soul in this dimension. Already she searched for his first victim. The problem was, there were none that were absolutely perfect to begin with. Don't get him wrong, she wasn't picky, but very few of these ponies would be willing to just give up their souls, and the ones that would were downright anti-social. He can't have that, no she needed a real social pony, he wanted the souls while they were still her's and only his.
She saw one that could be goaded, but few would listen to it. It was just too...Derpy. Another one would be easily corrupted, and would be perfect. If it wasn't so young. Slaneesh was starting to panic, what if the others saw her before he even got one soul? Was this world even worth looking at? Slaneesh kept looking over his shoulder like a child doing something wrong, and preparing to hide it as soon as a adult looked.
Then she found it. The first of many new cultist, Slaneesh giggled like a small child who has just cheated its way to victory, Yes, this bright pink horse will be the first pebble of the coming avalanche that will crush everything here.
