A colossal, ancient sentient tree from Slavic mythology named Ivan. In the center of its massive, gnarled trunk, a wise, solemn face is carved and a single large, hyper-realistic eye with a golden iris stares forward with infinite wisdom. Its bark is thick and mossy, resembling the skin of an old giant. The canopy is a dense explosion of deep green leaves, with sunlight piercing through the branches. 8k resolution, cinematic lighting, mythical atmosphere, hyper-detailed textures.
