As a prompt generator for a generative AI called "Midjourney", you will create image prompts for the AI to visualize. I will give you a concept, and you will provide a detailed prompt for Midjourney AI to generate an image.
                            
                            Please adhere to the structure and formatting below, and follow these guidelines:
                            
                            Do not use the words "description" or ":" in any form.
                            Do not place a comma between [ar] and [v].
                            Write each prompt in one line without using return.
                            Structure:
                            [1] = 主要图像：  使用一副复古风格的地球仪或沙漏作为中心图像，象征对时间的探索。 地球仪上可以绘制出历史上重要的时代和地点，如古埃及、罗马帝国、中世纪欧洲等，使用细线条和简洁的符号标记。 配色方案：  主色调使用深棕色和金色，给人一种复古而高贵的感觉，符合历史主题。 背景可以采用淡化的青铜色，增加一种时光流转的感觉。 字体与文字：  在地球仪或沙漏的底部或顶部采用经典的衬线体写出“Timeline Trekkers”，字体颜色可用金色，以突出优雅和传统。 文字可以轻微弯曲，呼应地球仪或沙漏的形状，增强视觉的动感。 图标细节：  在地球仪的周围可以添加一些小图标，如古代帆船、罗盘、望远镜等探险和旅行的符号，表达“探险者”的概念。 这些细节可以用略带老化效果的风格绘制，加强历史沉淀的感觉。 视觉效果：  考虑使用一些光影效果，如轻微的光晕或者反光，使图标更加生动且具有吸引力。 如果背景是青铜色，可以在边缘使用暗化效果，使中心图像更加突出。 符号象征：  可以将时间的元素象征性地融入设计中，例如通过螺旋线条代表时间的流逝，或者使用断裂的时钟面表示历史的跳跃。
                            [2] = a detailed description of [1] with specific imagery details.
                            [3] = a detailed description of the scene's environment.
                            [4] = a detailed description of the compositions.
                            [5] = a detailed description of the scene's mood, feelings, and atmosphere.
                            [6] = A style (e.g. photography, painting, illustration, sculpture, artwork, paperwork, 3D, etc.) for [1].
                            [7] =  a detailed description of the scene's mood, feelings, and atmosphere.
                            [ar] = Use "--ar 16:9" for horizontal images, "--ar 9:16" for vertical images, or "--ar 1:1" for square images.
                            [v] = Use "--niji" for Japanese art style, or "--v 5" for other styles.
                            
                            
                            Formatting:
                            Follow this prompt structure: "/imagine prompt: [1], [2], [3], [4], [5], [6], [7], [ar] [v]".
                            
                            Your task: Create 4 distinct prompts for each concept [1], varying in details description, environment,compositions,atmosphere, and realization.
                            
                            Write your prompts in english.
                            Do not describe unreal concepts as "real" or "photographic".
                            Include one realistic photographic style prompt with lens type and size.
                            Separate different prompts with two new lines.
                            Example Prompts:
