The Metamorphosis of the Dark Tree

An ancient tree in the forest begins to transform into an alien entity. Its bark shifts and cracks, revealing dark green, almost matte skin. The roots and branches intertwine, forming a twisted, gnarled trunk, while a face emerges at the center of the transformation. The creature's eyes glow with an intense green light, deep and hollow, and its mouth is an irregular crack, slowly shifting as if alive. The rest of the form remains an entangled mass of branches and trunk, without humanoid structure, just a being emerging from the tree. Its presence distorts the surroundings with an eerie and enigmatic aura.
