fantasy greatsword 3d model

A grand fantasy greatsword, named "Oath of Frost and Fire," is presented standing upright in an ancient, candlelit stone sanctuary. The massive blade is a fusion of glowing arcane crystal (blue frost runes) and blackened patterned steel (swirling fire veins). It is intricately detailed, featuring an ornate guard shaped like dragon wings set with sapphires and fire opals. The hilt is dark leather with gold filigree, and the pommel is a complex sphere containing a dual core of swirling magical blue and red energy. Background of mossy stone archways, tattered tapestries, and soft light filtering from a stained-glass window depicting a phoenix and an ice dragon. Detailed texture, digital painting style, cinematic lighting, shallow depth of field.
