Hello, I have a group of friends and their kids that really, \*really\* want to play in a game set in this book series’ setting. It doesn’t have its own ttrpg, but I figured that the YA tone would fit the PBtA system better than most others, what with characters having pets+superpowers and killing/death being rare. 

However, there’s an absolute assload of various PBtA game settings and I’m only familiar with Masks and Epyllion; could any of you give me a recommendation on any other setting books that might fit the theme better? 

The characters in the books are Apprentices to Masters; the Masters are further divided into jobs that are essentially Warriors, Scholars, and Prospectors (and Apprentices eventually hope to join one of the three). Race options are only Human; divided between Lorekeepers (Pet Tamers that get magic from bonded pets); and Elsies (non-magical, and extremely superstitious backwoods-types, that are more broadly skilled thanks to \*not\* relying on magic all the time).   
Pets are AtLA-style mashups of two or more regular animals and/or elemental effects (so literally anything you can think of) with a specific elemental-style magic attached (like the black dog on the books above being wind-based, with it and its Keeper being able to run fast, control gusts, and eventually turn insubstantial for brief periods). 

PBtA is not so complex that I probably couldn’t put together my own version, except my friends want to play \*NOW.\* So any guidance is appreciated!
