Amulet Trixie

In my HC, Sombra is what happens to a pony that wears the Alicorn Amulet, and he was once starryoak.deviantart.com/art/K… and a normal unicorn. The Alicorn Amulet was forged by Nightmare Moon's cult to transfer Nightmare Moon's soul to a vessel, but while it infused the power, it was corrupted and sucked away the humanity (equinity?) of its wearer, like the Ice Kings crown sucked his memories and sanity, except it took away the morals of the wearer. It would blacken their souls and turn them into cruel maniacal tyrants. They sealed it away in the Crystal Empire, were it was found by King Sombra, and the rest is history until the Amulet was moved to a secret shop for safekeeping, which turned out to be not so safe. This is what would have happened to Trixie if Twilight hadn't intervened.
