“JEJU”是使用 FontVibe AI 创作的维京卢恩文字效果。只用直线和 45 度斜线构成的棱角符文风大写字母，刻在冷钢灰色的石头上，头顶是极光夜空。

rendered in Elder Futhark runic letterforms — all strokes constructed from straight segments at horizontal, vertical, and 45-degree diagonal angles only; no curves anywhere, angular geometry derived from the physical constraint of carving into stone with a straight blade. Tall narrow proportions, strong vertical emphasis, sharp pointed terminals where strokes meet. Each stroke presents a flat angular face — illuminated and shadow faces alternate across the word creating the faceted highlight pattern of hand-carved letters. Pure runic geometry, powerfully ancient. JEJU forged in massive Elder Futhark runic letterforms — every stroke a straight-cut segment, horizontal, vertical, or 45-degree diagonal only, zero curves, pure angular geometry hammered into existence. Letters occupy dominant frame width, tall narrow proportions with strong vertical emphasis, sharp pointed terminals where blade-carved strokes converge, faceted highlight planes alternating illuminated and shadow faces across each character. Background: pure cold black void, absolute darkness with a faint northern horizon suggestion — deep charcoal bleeding into black. Lighting: single cold key light descending from hard upper-left angle, casting razor-precise geometric shadows from each letterform onto a flat polished dark slate floor plane — faint specular reflection of letter bases visible below. The carved faces of each stroke catch the cold light with clinical precision: bright angular highlight plane, immediate hard shadow face, no ambient fill softening the geometry. A ghost-thin aurora trace along the upper atmosphere — muted teal and steel blue, barely present, atmospheric rather than decorative. No particles, no fire, no organic texture, no weathering. Color palette: deep charcoal-black environment, ice-white letter highlights, cold blue-teal accent from the aurora suggestion, slate-grey shadow faces. Esports tournament-stage reveal energy — pure runic geometric authority, maximum cold power, the four letters as complete visual statement. Ultra-cinematic high-contrast render, 8K sharp, octane lighting quality.
