Tree in a Portal Chamber: Neon Digital Fantasy

A colossal ancient tree stands at the heart of a circular portal chamber. The chamber walls are translucent crystal panels set in polished metal, etched with faint circuitry and holographic runes. The tree's roots coil over a reflective floor as a swirling, multicolored portal hovers near the base of the trunk, casting prismatic light across mossy roots and glowing bark. Bioluminescent moss and leaves emit cyan and magenta hues, with particles drifting through the air and soft lens flares. Floating staircases and data streams appear in the air around the trunk; a starry ceiling glimpsed through the portal adds depth. Style: digital art, hyper-detailed, cinematic lighting with cyberpunk-fantasy vibes.
