I haven't played it yet, but the title piqued my interest for a very... odd? reason.
I have been using the term "perpetual broth" for years to describe my grandmother's soup that, much like in the world you've built, never ends due to her constantly topping it with everything in the kitchen that's nearing (or past) expiration.
My friends and I ever created a little legend that if anyone drinks the soup (it's an
untold rule, that one should never accept food from my grandmother), they will either die or be granted eternal life (the only explanation for her to still be kicking after drinking that thing... some of the things I've seen go into that... *shudders*)
Anyway, I hope you get a giggle out of my tidbit. Just wanted to share :)
