Grimm's School for the Erratically Gifted: Chapter 18
Little is known about what exactly happened during the time that Edmund spent with Victrola and Professor Whiskfield. The only available evidence comes from two sources: the events that occurred afterwards, and a small note in the margins of one of Edmund’s surviving notebooks:
I have done it! After much study, experimentation, and inspiration, I have concluded that it is possible to perform a post-encardiocephelographic revivification on a corpse of indeterminate duration of death, by adjusting a few ingredients and procedures involved in the creation of my ancestor’s Mechanus Vitae.
I have discovered a truly marvelous recipe for this, which this margin is too narrow to contain.
Scholars and medical professionals have struggled for years to discern exactly what this recipe is, to no avail. Many have used this lack of success to posit that Edmund was a bit of a prankster at this young age, while others suggest that, at its simplest, Edmund decided it was safer that no one knew the recipe apart from himself.
