Arc 2The Thorn Oath and the Institute
Murphy turned Lucius Malfoy’s arrest into a public and political victory, then built Umbrella’s research operation and used magic to recruit Muggle scientists under secrecy oaths. The arc left him seeking a teacher for the researchers as the Ministry began investigating his potion business.
- Murphy escaped the exploding Malfoy Manor, erased the memories of five Muggles, and used an anonymous video to expose officials trying to seize Umbrella’s drug formula.
- Murphy accused Lucius Malfoy of being a Death Eater, but the Wizengamot convicted Lucius only of crimes involving Dark Magic items and sentenced him to prison and fines.
- Murphy cleared his own accusations of arson and secrecy violations, hired Locke as his agent, and opened Supreme Potion shops while concluding that he would have to change wizarding society.
- Murphy expanded Umbrella’s research operations, recruited Serika Wood to develop a secrecy charm, and questioned Tom Riddle’s diary for spells that could protect secrets.
- Murphy learned the Thorn Oath from the diary, tested it on Serika, and used a false future history to unsettle the diary and make it reveal magical knowledge.
- Murphy completed Western Mansion and demonstrated magic to the scholars he had recruited, inviting them to study it at Umbrella’s No. 1 Spell Research Institute under strict confidentiality rules.
- Murphy had the researchers sign agreements and swear the Thorn Oath, while Dawlish alerted Scrimgeour to possible Beauty Potion sales to Muggles and Murphy sought a teacher for the researchers.
