dark fantasy greatsword 3d model

A massive black greatsword designed for a final boss in a dark fantasy game. The weapon is perfectly symmetrical and oversized, with a long, heavy silhouette. Made of an unknown obsidian-like material that absorbs light instead of reflecting it. No glowing effects, no colors other than deep black and very subtle dark gray. The blade looks ancient and cursed, with minimal cracks and carved details, suggesting a sealed or dormant power rather than active energy. The design should feel intelligent and oppressive, as if the weapon itself has a will. No decorations, no gold, no symbols of royalty — only raw, ominous presence. Clean, solid shapes with a slightly brutal and monolithic structure. 3D model, game-ready asset. Clean topology, mid-poly count. Centered, neutral orientation. No background, no environment. Designed for use in a fantasy game character boss.
