Anything lore-wise told outside of the FiM show, (such as G5, the comics, journal of the two sisters, etc) unless stated otherwise by the fic itself, is considered non-canon to avoid continuity issues.
This Fic takes inspiration from many shounen stories and, while the author made sure that most of, if not all plot-points make at least some sort of sense lore-wise, some story elements are crackfic-level in terms of absurdity. (What I'm trying to say is things are probably going to get REALLY stupid).
And there will be no exact times that Crusaders will update, as the author would rather tell the story at his own pace.
Thank you for reading!
