"Then came the fateful day when Blagdon Blay, a wizard who had been burgled 19 times in two weeks, succeeded in inventing an Anti-Alohomora Charm. In a single night, the wizarding doors of London were sealed shut, and task-forces were dispatched to protect Muggle houses, too."
Miranda Goshawk, Book of Spells.[src]

Blagdon Blay (fl. early 1600s) was an English wizard and a Londoner in the early 17th century who was responsible for the creation of the Anti-Alohomora Charm — effectively stopping a series of burglaries by wizards using the then-innovative Unlocking Charm.[1]


When thief Eldon Elsrickle introduced the Unlocking Spell (which he had learnt from an ancient African sorcerer) to London, there was an unprecedented series of recurring burglaries and break-ins by unscrupulous wizards, upon the homes of Muggles and fellow wizards alike.[1]

Blagdon Blay had his house broken into nineteen times in the course of just two weeks. He managed to develop an Anti-Alohomora Charm to secure his house, and soon all the London wizards sealed their houses shut at night, and special wizard task-forces protected those of Muggles.[1]

Magical abilities and skills

  • Charms: Blay was highly accomplished with charm-work, having successfully invented the Anti-Alohomora Charm, which he ingeniously used to prevent locks being broken with the Unlocking Charm and preventing theft, to great success.
  • Spell creation: Blay succeeded in the highly difficult magical art of inventing new spells, having invented the immensely useful Anti-Alohomora Charm, an excellent magical achievement given the success of the charm.
