Amidst the ruins of a futuristic battlefield, Cortana's holographic form flickers to life from a broken AI terminal, her image unstable but glowing with determination. Her body is formed of fragmented data streams that weave together, creating a luminous, otherworldly presence. Around her, sparks and debris float in zero gravity, illuminated by her soft blue light. She extends a hand as if reaching out, her voice urgent yet resolute, guiding a lone survivor through the chaos. The scene is dramatic, with an air of hope and resilience.
