古びた羊皮紙に描かれたファンタジー耐火マントのイラスト

A Dungeons & Dragons–style fantasy illustration of a fireproof cloak displayed as a magical item on aged parchment. The cloak is deep dark red, made of layered fabric embossed with a subtle dragon-scale pattern, trimmed in ornate silver threading along the edges and clasp. The cloak hangs naturally as if on an invisible form, slightly billowing, with restrained magical warmth implied by faint ember highlights. Rendered in the official D&D 5e art style: painterly realism, muted colors, soft shadows, fine brush texture, medieval fantasy illustration. Neutral parchment background with light wear, ink stains, and vignette edges. No characters, no modern elements, no glowing effects, no photorealism.
