Can we take a moment to appreciate the genius of a Harry Potter and Community crossover played vaguely straight? We could even have Pierce cameo as an instructor or something, being a real Laser Lotus. You’d have to work a bit to keep it from feeling too derivative, but there’s some fun potential here. Maybe put in a little bit of Broken Masquerade to justify the existence of a community college of magic, too. Plenty of fun options.
The familiar has been popularized in the modern era by those who play Dungeons & Dragons, as well as countless medieval based games where being awesome isn’t enough, you’ve got to have a rabbit or whatever that blows flame out of its ears.
