「FENRIR」は FontVibe AI で作成したバイキングの文字エフェクトです。彫り込まれた石のテクスチャ、北欧のノットワーク模様、戦いで傷んだ金属の質感、そして古代スカンジナビアの美意識をまとった、北欧バイキングのルーン文字タイポグラフィです。

ancient Norse warrior aesthetic — stark angular geometry, battle-forged weight, the material permanence of things built to outlast kingdoms. Directional forge-light or cold torch-light that sculpts every letterform face into high relief. Color palette: iron-grey, aged bronze, cold granite, dark amber — no soft pastels, no unmotivated gradients. Every letter reads as an object with real physical mass. When no specific material is defined by the font: default to battle-worn dark iron — cold charcoal-grey letter body with visible forge-hammer surface texture, narrow cold specular highlight on the upper stroke edge, deep iron shadow on the underside, hairline stress-fracture lines along diagonal strokes. The Norse blacksmith's iron: heavy, angular, built for war. 'FENRIR' as precision Elder Futhark angular runic letters filling 75% of frame, centered. Maximum angular geometry — all strokes at exactly 0°/45°/90°, blade-cut flat terminals, no curves anywhere. Letter body: pure matte black geometric forms. Background: smooth aged off-white illustration board or tattoo stencil transfer paper — fine grain texture, cream-white with slight warm ivory tint. A tattoo artist's fine-liner pen rests just outside frame edge, barely visible. Cold clean overhead daylight from directly above — maximum contrast, zero shadows. Atmosphere: tattoo flash design sheet, Norse tattoo artist reference stencil, high-contrast reference artwork. 1:1 square format.
