Celestia loves Twilight Sparkle. That is a fact, an indisputable constant of the universe. What that love means, however, is much less certain. The love of a teacher, the love of a friend, or the love that Celestia dares not name.
For as long as she can remember Twilight Sparkle has enjoyed The Hunt. Her mother taught her that, even if they feed on the lifeblood of ponies, the hunt is always the best part. Now, Twilight is on the hunt for somepony, and that pony is Starlight.
