A humanoid tree spirit emerges with a slender, yet robust, frame crafted entirely from twisted, ancient-looking bark and gnarled branches. Its skin is a deep, earthy brown, textured with rough, fibrous striations, while patches of vibrant moss and small, emerald leaves cling to its shoulders and head, serving as natural hair. Its eyes glow with a soft, inner amber light, contrasting with the dark, woody surface. The spirit's form suggests a blend of organic growth and humanoid grace.
