The Void Keeper

At fifteen, Kael was given a Rank F Elo — Spatial Storage. A small gray portal, barely the size of a bowl, leading into a personal void that only he could access. No flames. No shockwaves. No offensive application. The Guild assessors moved on before he even left the room. While ranked adventurers fight monsters and build reputations, Kael runs deliveries, carries medicine across dangerous roads, and spends every spare hour training with weapons no one thinks he needs. But the Void is growing. Slowly. Quietly. And Kael is learning exactly what it means to be the only person who controls a private dimension — with instant access to everything he's ever stored, and the patience of someone who has never once been taken seriously. The world keeps calling it a useless power. He's in no hurry to correct them.
