In the heart of a dense, mystical forest, an ancient Tree Ent, a towering, humanoid tree creature, stands guard over a glowing portal. The portal emits radiant, pulsating light in shades of violet, pink, and blue, casting surreal reflections on the moss-covered forest floor. The Tree Ent's bark-like skin is intricately detailed, covered in vines, moss, and glowing runes. Its glowing eyes and twisted limbs give a sense of ancient wisdom and power. The forest background is dark, with beams of moonlight filtering through the trees, illuminating patches of mushrooms and bioluminescent plants. The scene is captured in a medium close-up shot, emphasizing the magical portal and the Ent’s towering, protective stance. The style blends realism with fantasy, creating a mystical and slightly eerie mood.
