The boredom of Thursday evenings gets to Twilight Sparkle, and she decides to create a fun meet-at-home club.
The problem is that she doesn't create a book club. Seriously Twilight. You're a librarian. I mean, come on. Book club didn't occur to you?
Sigh... no. Twilight's idea is Cauldron Club! Yes, Cauldron Club! Cute name for a potentially catastrophic alchemical disaster, isn't it? Now anyone with a desire to dabble in the arcane and... disturbingly reactive world of potion-making can gather in a single place to celebrate their mad science harmless hobby!
Potion-making can be a dangerous hobby, Twilight. More-so if that hobby is shared. What could go wrong?
Oh, and... bring your own cauldron.
This story takes place between "Keep Calm and Flutter On," and "Magical Mystery Cure," and so features unicorn Twilight.
