Chapter 1: Blood Upon the Sands

Urbosa was many things, but even she could not halt the sands of fate. When a dying Hylian mother entrusts her infant son to her, begging on her last breath to raise him as her own, her Gerudo pride could not possibly deny her final request. Link, despite being a male, would be raised Gerudo. And Urbosa would make sure her son would be the strongest warrior of them all.
