In the center of the scene, a tomb guardian crafted from an unknown metal stands before a massive extraterrestrial monument. Its figure is tall and resolute, with eyes that seem to pierce through time and space, gazing into the endless darkness beyond. Its surface is adorned with complex symbols and patterns, each seemingly carrying the secrets and tragedies passed down for thousands of years on this land.  Surrounding the tomb guardian are the forgotten extraterrestrial graves. The "tombstones" here are no longer stone or metal but variously shaped and worn objects by time's erosion. They might have once been symbols of civilization, now silently narrating the tales of demise and decline.  The night wind blows gently, bringing with it coldness and desolation, yet the tomb guardian stands firm as if waiting for something, or perhaps guarding some eternal entity. Its deep-set eyes seem to hold a power beyond time and space, prompting one to contemplate: Who does this tomb guardian exist for? Or maybe, it is just an isolated mournful being in the universe, silently witnessing the cycles of all things.  In the background, distant galaxies appear particularly tranquil under the cloak of night, forming a stark contrast with the figure of the tomb guardian. Such a scene inevitably leads to contemplation of the secrets hidden at the farthest reaches of the cosmos and those entities that transcend human understanding. 8k,uhd,hdr,best quality,hyper detail,ray tracing,cinematic feel,professional photography lighting.  midjourneyv6.1.
