Necromancy is a form of magic that involves raising the dead, usually for an evil or unnatural purpose. This is not the story of an evil necromancer, but the Memoirs of one Renovator Caesorum, a name that, in the oldest of pony languages, means Raiser of Fallen. He invented great spells in an attempt to understand the afterlife, something that nopony has done since. History has forgotten him, but his book is found and translated by Twilight Sparkle, who quickly becomes surprised at his experiments.
