Its colossal, gnarled roots, thick as castle walls, twist and weave across the sacred earth, their surfaces inscribed with glowing runes of an extinct civilization. The bark, a mesmerizing blend of deep obsidian and radiant gold, pulses faintly, as though the tree itself breathes with an eternal spirit. Its canopy stretches beyond the heavens, leaves shimmering in a cascade of iridescent blues and greens, each one softly glowing like a fragment of a lost constellation. Luminescent vines drape from its massive branches, whispering in an unheard, ancient tongue as they sway in the warm, enchanted breeze. At the base of the tree, an ethereal pool of liquid light reflects the cosmos itself, rippling with images of past and future events. A lone traveler, clad in tattered robes of a forgotten order, approaches the pool, his reflection shifting between ages long past and destinies yet to come. Above, the sky swirls in a celestial dance of auroras, casting soft beams of silver and violet light onto the sacred clearing. The air hums with the sound of distant celestial choirs, as if the universe itself acknowledges the presence of this timeless guardian.
