As a writer, you should try to give your villains plausible motivations, backstories, etc. A villain is much more interesting if they think they’re the hero of their own story.
As a DM, this is still great advice in theory but in practice you should ABSOLUTELY NEVER DO THIS because your players will discover your villains’ tragic backstory, look at their motivation and find it sound, and end up adopting the villains, going rogue from the Celestial Intervention Agency to avenge the wrongs done said villains and ensure their freedom, accidentally kidnapping the President, and plunging Gallifrey into a civil war.
This lady can’t afford six eggs, which always struck me as a little odd but I figured maybe that was normal in a poor French village. I mean, look at all the little kids she has; she probably struggles to afford any kind of food that would feed all of them… Right?
But later we discover something interesting about Gaston:
Gaston eats five dozen eggs every day. That’s 60 eggs. SIXTY. Which adds up to 420 eggs per week. No wonder this poor village doesn’t have enough of them to go around!
Gaston, who is very well-respected and successful and probably makes good money from his fabulous hunting skills, is cornering the entire egg market. To feed his addiction, he probably has to constantly go around and buy out every farmer’s supply of eggs, which causes the price on any remaining eggs to skyrocket.
Gaston is singlehandedly destroying the town’s economy.
Way to go, Gaston. You may be popular, but I’m sure that at least the chicken farmers were relieved when you fell to your death.
