A detailed illustration of two characters from a romantic and mystical story. The first character is a powerful goddess, Mẫu Đệ Tam Thoải Phủ, depicted with a regal appearance. She has long, flowing black hair and is wearing a traditional Vietnamese áo dài in shades of blue and silver, symbolizing water and mystical elements. She has a calm and confident expression. Beside her stands the second character, a young girl named Linh. Linh has long black hair and is wearing a simple white áo dài. She has a curious and admiring look on her face as she gazes at the goddess. The background is a soft, dreamy representation of a tranquil river scene with shimmering water and soft moonlight.
