Ch. 306Prima Materia Reveal
Murphy learned that the Philosopher’s Stone required a rare substance called prima materia and studied a spell for detecting it. He realized that magical scanning technology could make the search far more practical.
- Murphy had Aurors break into the Headmaster’s Office after Dumbledore left without handing it over, and Snape used part of it as a potion lab.
- Murphy arrived by lightning with the Lightning Raven’s help, accidentally ruining Snape’s potion, and promised to reimburse him.
- Snape reported that the Elixir of Life suppressed magical power and that making a Philosopher’s Stone required prima materia, which Nicolas Flamel had found only once.
- Snape gave Murphy Flamel’s prima materia detection spell, and Murphy learned and tested it.
- Murphy calculated that the spell would make searching vast areas impractical, then considered compressing its range and amplifying it with an array antenna to create a magical scanning radar.
