“XASTHUR”是使用 FontVibe AI 创作的哥特字体文字效果。严谨的 Textura 哥特黑体：窄长的折笔、菱形笔端和强烈粗细对比，黑墨带金色描边，写在深色旧羊皮纸上。

rendered in precise gothic blackletter letterforms with authentic calligraphic construction — diamond-shaped stroke terminals, strong thick-thin contrast, pointed arch counters. Rich black ink with warm depth on dark parchment or deep charcoal background. Subtle gold ink highlights on serifs and capitals. Medieval scribal precision. No cobwebs, no rust, no atmospheric fog — pure typographic craft. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the rich ink, the parchment ground and the subtle gold highlights. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as precise gothic blackletter in rich black ink with subtle gold highlights on dark parchment — pure typographic craft, no cobwebs, rust or fog. COLOR PRIORITY: keep the font's own colors if specified; otherwise black ink with warm gold accents. Square composition with “XASTHUR” as the sole, unmistakable focal point, centered in a dense, commanding arrangement with generous dark negative space around the word. Give the lettering a forged-iron presence: deep black metal, rough hammer marks, pitted rust, and muted brown-red patina along the edges, with restrained antique-gold glints on a few sharp corners. Fine cobweb threads cling between letter edges and the surrounding stone, sparse enough to keep every character clear. Behind the word, a tall pointed cathedral arch emerges from near-black carved stone, its silhouette catching a dim crimson backlight that forms a sinister halo without washing out the iron. Subtle candlelike side light grazes the uneven metal and reveals its weight; the rest recedes into deep charcoal shadow. Keep the background spare and dark, with no extra lettering, ornaments, or competing focal points. The overall impression is severe, medieval, and ominous: precise typographic craft set against a forbidden Gothic threshold.
