Martha, a wise and ancient member of the Tree Folk. Martha should be depicted as a humanoid figure with bark-like skin, resembling the texture and color of an old, majestic tree. Her hair should be a cascade of vibrant green leaves, flowing down to her shoulders. Her eyes should be a deep, earthy brown, reflecting the wisdom and serenity of the forest. Martha is dressed in simple, natural attire made from woven vines and moss, adorned with small flowers and berries. She holds a staff made from a gnarled branch, topped with a glowing crystal that emits a soft, ethereal light. The background should be a lush, enchanting forest with towering trees, dappled sunlight filtering through the canopy, and a carpet of ferns and wildflowers on the forest floor. Small, magical creatures like fairies and woodland animals should be visible in the scene, adding to the mystical atmosphere.
