Fantasy books thrive on imagination, but the best ones anchor their wildest ideas in emotional truth. I'd start by asking what fascinates me most—is it mythical creatures, intricate magic systems, or political intrigue in made-up kingdoms? Lately, I’ve been obsessed with the idea of a world where memories are currency, traded like gold. Picture a thief who steals not jewels, but someone’s happiest moments, leaving them hollow. The story could explore what happens when they accidentally take a memory that wasn’t meant to be seen—a royal secret that sparks a rebellion.
The magic system would need rules; maybe memories fade if not 'stored' properly, or certain emotions corrode the thief’s mind over time. The protagonist could grapple with the ethics of their trade, especially when they uncover a conspiracy tied to their own forgotten past. Side characters might include a memory-hoarding noble who’s literally drowning in nostalgia, or a rebel whose missing memories hold the key to overthrowing the corrupt system. The setting? A city built vertically, where the rich live atop towers literally 'above' the poor’s suffering. The higher you climb, the more pristine—and artificial—the world becomes.
