Valorous Leader Horseback Dressed Intricate Armor

Create an image featuring a valorous leader on horseback, dressed in intricate armor with a distinct emblem on their chest. The background should feature a battalion of soldiers in varying armor colors, on horseback, with banners waving high. The sky should be a dramatic gradient of oranges and purples, hinting at dusk. Replace the leader's helmet with a unique design that includes feathers and add subtle markings on the armor for a tribal vibe. Exclude any specific brand references and ensure the setting feels epic and historical.
