The Rainbow Factory is said to be a part of Cloudsdale's darker history that is kept hidden from most in Equestria but once chosen "failure" is destined to die, having no means of escape. For much of the story there is no mention of Rainbow Dash herself, but she is revealed near the end as the authority behind the Factory and in contrast to her heroic nature in the show she is seen as a sadistic, genocidal Social Darwinist who wants nothing more than to continue the Factory's bloody "cleansing" of Cloudsdale, seeing the mass-murder of "failures" as a part of keeping order and ensuring things stay as they should.

LET ME KNOW IF I SHOULD EDIT THIS SORRY IF ITS BAD LMFAO
