Enchanted Sword in Zero-Gravity

Photorealistic rendering of an enchanted sword floating in zero gravity within a vast, star-studded void. The blade is flawless steel with a razor edge, etched with glowing cyan runes that emit a soft, magical glow. A faint aura surrounds the weapon, reflecting on the brushed metal and revealing micro-scratches and subtle fingerprints. The ornate hilt features a dark leather grip and an intricate crossguard shaped from intertwined mythic motifs. Tiny motes of light and dust drift weightlessly around the sword, tracing delicate orbital paths. In the background, a distant nebula orbits softly with distant stars, and a cinematic backlight highlights textures and depth, producing realistic reflections and a sense of weightlessness and wonder.
