Create a finished vertical event poster, 2:3 ratio, for a Viking reenactment fair. Use a deep charcoal-black exhibition-stage environment with a flat polished slate floor at the bottom. A cold northern key light from upper left creates crisp, hard-edged shadows on the floor; place a very restrained deep-teal and cold-blue aurora-like wash only along the high horizon. No moss, rust, weathering, organic texture, smoke, fire, battle imagery, or decorative clutter. At the top, centered in small clean sans-serif text: “VIKING REENACTMENT FAIR”. The central 52% of the poster is a tall pure-white rectangular title field, sharply edged, with the exact headline “LONGSHIP DAYS” across two centered lines. Render every headline glyph as custom Runic Angular lettering: tall narrow proportions, heavy monoline strokes, every stroke only horizontal, vertical, or exact 45-degree diagonal; no curves, arcs, rounded corners, gradients, shadows, glow, or material texture. Substitute all normally curved Latin characters with angular rune-like equivalents while retaining readable English word recognition. Matte-black strokes on the pure-white field, blade-cut flat terminals and hard angular junctions, sparse technical-drawing clarity. Below the title field, place a single minimal black longship silhouette on the slate plane: straight segmented hull, striped square sail reduced to angular line geometry, no ornate carving. The ship is a secondary hero prop, centered and small enough to leave the lettering dominant. Under it, in spaced white sans-serif: “SATURDAY 26 SEPTEMBER 2026”. Then: “NORTH HAVEN WHARF · 10 AM–6 PM”. At the bottom, a narrow teal rule and tiny white all-caps line: “WEAPONS • CRAFT • LONGSHIPS”. Use a strict centered poster grid, broad black margins, high contrast, precise print-ready edges. The white title field is the brightest object; the surrounding charcoal stage and restrained teal horizon amplify it without competing. Ensure all text is correctly spelled and fully legible.
