Okay so basically there are two guys henry emily and william afton they start a family pizza restaurant together called fredbear's family diner, one day william locks henry's daughter charlie out of the restaurant and murders her outside, as seen in the fnaf 2 save him minigame and the security puppet minigame. charlie's soul goes on to possess the puppet animatronic. then in 1983 william's youngest son dies in hospital after being bitten by the fredbear animatronic as seen in fnaf 4, which causes fredbear's to close and the springlock suits to be decommissioned. the bite victim's soul goes on to possess the fredbear suit due to the suffering he sustained from the suit (this is explained in more detail in the fazbear frights epilogues). freddy fazbear's pizza is then opened. in 1985 william afton kills 5 more kids in a freddy's, and their souls go on to possess chica, bonnie, freddy, foxy, and golden freddy/fredbear (which now has 2 souls possessing it, directly paralleling the stitchwraith from the book series). that restaurant closes down but freddy's gets rebranded and has a grand reopening in 1987 as we see in fnaf 2. meanwhile, william opens circus baby's pizza world, featuring kid killing animatronics, however his daughter elizabeth gets killed by one of the animatronics (baby) and goes on to possess her. william sends his oldest son, michael, to go free her from the facility, as seen in sister location. back to freddy's - the fnaf 2 location stays open until the bite of 87, in which it's implied nightguard jeremy fitzgerald gets his frontal lobe bitten off by one of the animatronics. then fnaf 1 happens in a location that exists in 1993, not much lore there. after the 1993 location gets closed, william gets springlocked in the spring bonnie suit inside the abandoned building, becoming springtrap. Back to Baby in SL. Michael, after a week of working there gets lured to the scooping room by Baby in order to get his insides become outsides so that all the Funtime animatronics (now fused into Ennard) can use his body as a fleshsuit to escape the facility. Over time the suit starts to get rotten and more and more decayed. Michael body now turns purple and draws more attention (Note: there are now two purple guys, Miachel Afton, who is litterally purple due to decay in his fleshsuit, and William Afton, who isn't litterally pruple but the purple colour signifies him hiding in the shadow.) and the Funtime animatronics now as Ennard have to abandon ship in
