Most of you are asking me when and where the event happens in this version of FNaS?

Silent's "Player" Real World *Actual Reality*, aka.
Sonic Forces: Afterwards Alacrity "Different Dimension" is in year 20XX
(I emphasize: "Different Dimension" = different timeline/universe)
*Also this is after Sonic Forces "Different Dimension" *
While, Fiercy Forces is taking place:
In Silent's Computer ➤ In World of Five Nights at Sonic's "Different Dimension"
➤ In Dr. Golden's "Preparation" Citadel
➤ In Fiercy Forces Arcade Machine ➤ Is set in year 2031

And also...

Hmm... How to tell it in short.
Ok, so basically FNaS: Fiercy Forces series is a fan-project made by me.
The perspective is told from the view of the "Player", aka. Silent The Wild Lynx from the "Real World", aka. Sonic Forces: Afterwards Alacrity "Different Dimension". While the Original events from FNaS 1-5 and Maniac Mania did happen (that is, when Silent was playing the games on her Computer).
After Maniac Mania "Different Dimension", that is (becasue this Maniac Mania happens in another "universum")... the event has triggered and thus, Fiercy Forces has started (Then as well, Silent creates her "Avatar" cybernetic version of herself to interact with events happening there), Silent "Player" became the Main Protagonist and stands now against Dr. Golden "Preparation" and his Evil Forces to prevent him from invading Silent's *Actual Reality*. Yea I know it's too much to talk everything, but there's the stroy in short. I'll just need time on this one, and everything will be shown and tell anyways.

Fun Fact:
Also remember, that this Five Nights at Sonic's version of mine is my take on and a parody and have some other references from other games as well...
