The Story of Zeri
Zeri grew up in Zaun's working-class undercity, in a family that built their lives around community and mutual care. Her electric magic appeared early — uncontrolled, dangerous, accidentally shorting out neighbors' equipment and occasionally shocking her relatives. Her family didn't treat it as a curse. They treated it as something to learn, together, until she had it under enough control to be useful rather than destructive.
That community — Zaun's working class, ground down by chem-baron exploitation and Piltover's indifference — is what Zeri fights for. She's not a trained soldier, not nobility, not an ancient warrior. She's a kid from the neighborhood who got powers and decided that having powers comes with responsibility for the people around her. Her speed and lightning make her effective; her anger at injustice makes her relentless.
Zeri moves through Zaun like a current through copper — fast, direct, and heating up everything she passes through. She's learning the limits of what she can do and what she can't, which problems can be solved with a bolt of lightning and which ones require something slower and more political. She doesn't have all the answers. She has the determination to figure them out, and the knowledge that her community is worth the effort.
