I'm currently working on a story in which every single person in a certain city gets amnesia simultaneously. Basically, before the start of the story, it was a town where a subset of the population had psychic powers, and these were widely acknowledged and made use of. A group of non-powered villains decide that it'll be easier for them to accomplish their goals if no one has psychic powers anymore, so they design a magical bomb to destroy psychic abilities. Unfortunately, the bomb turns out to have a bigger impact than intended - everyone loses all long-term episodic memory, and anyone with psychic powers or who've had their mind altered by psychic powers ends up with serious mental disabilities. So far, I have a group of people getting everyone to meet up at a certain landmark so they can figure out who has valuable skills (because procedural memory is unaffected) and assign them the appropriate jobs to ensure that as many people as possible survive. The protagonist ends up becoming one of the caregivers for the disabled people, because she mistakenly thinks her brain-injured psychic younger brother had a preexisting mental disability, which would suggest that she has experience caring for disabled people. (She thinks this because he's wearing a diaper, which is actually because he's a bedwetter.) What would be some other issues faced by the setting?
