Which Books Or Comics Mention The Aftons Storyline?

Okay, here's how I see it after digging through the games and piecing together the minigames, tapes, and hints: the Aftons are essentially the family at the center of the whole haunted-funtime mess. William Afton is the core villain—he’s the man responsible for luring and murdering children (the purple-suited figure in the minigames), the one behind Afton Robotics and the creepy animatronics. He later gets trapped in a spring-lock suit and becomes Springtrap/Scraptrap, which is shown pretty clearly in 'Five Nights at Freddy's 3' and later references. His children factor heavily into the tragedy. Elizabeth Afton gets too close to Circus Baby and is killed, her spirit tied to Baby. Another child—the young boy who gets bitten in 'FNaF 4' (the so-called Crying Child)—is also part of the family tragedy. Michael Afton is the son who goes on a path to undo his father’s crimes: he’s the one who enters the sister location, becomes Ennard temporarily, and later is strongly implied to be the protagonist working to salvage and free the trapped souls in 'Sister Location' and 'Freddy Fazbear's Pizzeria Simulator'. Some edges are fuzzier—how exactly the souls attach, who ‘Cassidy’ is in canon versus fandom, or which endings are fully definitive—but the backbone is consistent in the games: William is the killer and haunted corpse inside a suit, and his children become victims, agents of vengeance, and the ones trying to put things right. For anyone tracing the lore, following the minigames and the later narrative beats in 'Sister Location' and 'Pizzeria Simulator' gives you the clearest canonical map, even if Scott peppers some poetic ambiguity along the way.
