Create a finished vertical 2:3 fantasy novel cover. The exact printed text is: headline “The Spellbinder's Oath”; supporting line “One oath can unmake a kingdom.”; small genre line “AN EPIC FANTASY NOVEL”; author line “MARA VELL”. Render no other readable words. Set the headline in large, highly legible Celtic knotwork display lettering: each letter stroke is a continuous, physically broad ribbon interlaced in alternating over-under loops, with the letter skeleton clearly readable. Give the ribbons the depth of carved dark stone and tooled leather, narrow antique-gold edges, tiny surface cuts, spiral and triquetra terminals, and purple-gold light glowing within the crossings. Preserve the font’s material and interlace logic; add a soft magical halo around the letterforms. Cover composition: small genre line at the top; headline dominant across the upper third, stacked into balanced lines; central scene occupies the middle; supporting line near the lower edge of the scene; author name centered at the foot. Use ample margins and clear separation between lettering and scene. In the central scene, a hooded spellbinder stands in a towering ancient library, holding an open spellbook at chest height. A single luminous gold thread arcs from the book to a small oath-seal, while nonalphabetic glowing runes orbit the headline in curved paths with fine gold particle trails. Add floating page leaves, purple mist, candle flames receding between dark bookshelves, and wisps of magical smoke. Deep shadow anchors the scene; purple and gold light interplay across the letters and subject, with dramatic upward light from the book, candle flicker in the background, and restrained rim light on the figure. Render detailed stone, leather, paper, and smoke textures; maintain strong title contrast and crisp, accurate lettering. No square layout, no extra text, no logos or border.
