Ancien arbre bioluminescent dans un paysage alien brumeux

A colossal, ancient tree with bioluminescent roots that spread across a misty, alien landscape. Strange, floating islands drift in the sky above, connected by shimmering, ethereal bridges. The air is filled with tiny, glowing spores. The style is reminiscent of dark fantasy concept art, with intricate details and a moody, atmospheric lighting, inspired by the works of H.R. Giger and Zdzisław Beksiński.
