P.S. What is a necromancer? I can’t find anything about them.
Celestia sighed, looking down at the letter. She should have known that her former star pupil would be curious. With most of her own response already finished, the Princess was tempted to ignore that postscript altogether…
…No. Twilight could be trusted.
Sincerely,
Princess Celestia
P.S. Necromancers are magic users like unicorns, channeling the power of life and death from the shadow world through objects like books, candles, daggers, and bells. Bells in particular are specialized for creating, controlling, and containing disease. Necromancers like Grogar were once called plaguecrafters.
