"Create an image showcasing a stylized, minimalist silhouette of an ancient, gnarled tree at dusk. The tree, appearing old and dry, should be centered, with its twisted branches reaching upwards and its thick roots visibly spreading deep into the earth, embodying resilience and the passage of time. The background should be a gradient, blending from a dusky, aged parchment color at the top to deep, dark soil tones at the bottom, hinting at depth and mystery. Above the tree, in a rustic, vintage-style font, add the word 'Underground'. The overall feel should evoke a sense of time-worn mystery and the hidden stories of the earth beneath our feet."
