Envision intermediate creatures as ethereal beings with gentle human features and serene expressions that reflect deep wisdom. They possess an elegant stature and harmonious proportions, blending physical strength with spiritual grace. Their eyes emit a luminous glow beyond ordinary color, perhaps a celestial blue or vibrant green, indicating their semi-angelic nature. The skin of these creatures has a subtle radiance, as if reflecting light from a realm not entirely of the material world. Though wingless, their presence is marked by a soft aura of light, suggesting they are enveloped in a cloak of pure energy. They wear simple yet elegant garments made of fabrics that seem to shift in color and texture with movement, complementing their intermediate nature between the material and spiritual realms. In their hands, they may hold symbols or artifacts representing their role and purpose in the universe, items that appear to be crafted from materials unknown on Earth, glowing with an inner light.
