"Create a high-resolution image of a large, highly polished titanium plaque with a sleek and futuristic appearance. The plaque should solely feature a collection of embossed non-terrestrial symbols and text. The symbols and text should give the impression of an advanced non-terrestrial civilization's cohesive written language. Ensure that the symbols and text are consistent in style and size and are not directly based on any Earth languages. The non-terrestrial text and symbols should appear embossed, giving the plaque a three-dimensional look. The overall visual composition should be balanced and aesthetically pleasing."
