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. 'YGGDRASIL' in clean Elder Futhark runic letterforms, wide composition. Background: minimal cold stone surface, soft diffused northern light from above. Cultural-educational presentation quality — like a museum exhibit panel. The letters demonstrate genuine Norse textual tradition. Scholarly, minimal, culturally authentic.
