"Life works in mysterious ways, lady Rarity. Most of the time neither my sister nor myself know just why certain events happen. Why the life of a young and promising filly has to be abruptly ended while the elder keep on living? Greater forces than the sun and moon are at hoof for that. That is our best guess for your situation. At least that we can give you in a form that you can still understand it," replied Luna before she glanced out of the window. "Unless you would like to question your every belief, we shan't discuss the matter further."
