Forged from a spark of Thor's lightning and tempered in the waters of ancient battlefields, Valor's Harbinger emerged as a divine entity capable of recognizing the potential for heroic deeds before they occur. Thor bestowed upon it the sacred duty of identifying and heralding those moments when a warrior's courage would be tested to its ultimate limit, ensuring that no act of true valor goes unwitnessed or unrecognized.

Valor's Harbinger possesses the unique ability to sense the gathering storm of courage within warriors' hearts, manifesting as a resonating thunderclap that draws attention to impending acts of exceptional bravery. It can appear simultaneously at multiple locations where valor is about to be tested, its presence serving as both challenge and witness to those who would prove themselves worthy. The entity's power grows stronger in proportion to the magnitude of courage about to be demonstrated.

Within Thor's champions, Valor's Harbinger serves as a divine witness and announcer of heroic potential, identifying those moments when warriors have the opportunity to prove their worth through exceptional acts of courage. It helps guide Thor's attention to those most worthy of his recognition and Valhalla's halls.
