So basically, I found an AU prompt detailing an alternate timeline divergence of the Matoran Civil War.

On Tumblr. Yeah. - https://www.tumblr.com/custombonkles/163899974172/au-prompt-matoran-civil-war?source=share

Basically, the prompt details about what would happen if the Brotherhood of Makuta chose not to intervene. The resulting series of events is somehow even more catastrophic than canon, to the point where even several of Mata Nui's lower functions would shut down and the sky domes would glitch, among other things.

I'm not joking, it actually does exist! Go give the link a visit.

If it got bad enough, then the Order of Mata Nui would probably step in. Or just the Toa.
