Re: other things that could be zc plots
brainstorming without filter here, but i could volunteer daphne to brainchild/concoct some of the magical mishaps, like the aging-deaging (BREAKING THE TIME-SPACE-MAGIC CONTINUUM YAAAAAH) or truth serums. maybe controlling the floo network and making it go haywire? maybe people mysteriously disappear or "get stuck" in the floo network? idk. another mishap could be a broken wards thing. maybe it was a corroboration between wicon and zc?
a vague idea i had was an ed-snowden-esque leak of classified ministry information? or like, the emergence of a wikileaks/"whistleblower"-type of hub? maybe an unreleased-to-the-public dark magic weapon from CERN is stolen?
