A powerful spell (Ponytober day 4) · 4:57am Oct 5th, 2021
This was inspired by the prompt for Ponytober day 4: a powerful spell. I figured that I should make some dumb nerd physics joke. And I was right.
If you're one of the lucky few that don't know, Derpy's referencing mass-energy equivalence. That's the joke. Hell yeah.
