Create a captivating and intricately detailed henna-inspired tattoo that gracefully trails down the spine of a dark-skinned female character. The design must incorporate the word "unwavering" into the pattern, representing her formidable inner strength and tireless resilience. The artistic elements should flow harmoniously, distinctly showcasing the beautiful complexity of henna artistry, while the positioning emphasizes the length and curvature of the wearer's back.
