"Edge of Eternity" A poster for a sci-fi thriller. A lone astronaut stands on the edge of a crumbling alien cliff, staring at a colossal black hole tearing apart the sky. The tagline glows in metallic lettering across the top: "When time ends, only the brave remain." Fractured debris floats upward around the astronaut, and the deep blues and fiery reds of the black hole swirl dramatically, pulling the viewer into the image.

Amethyst Sky Train Through the Stars A futuristic train made of sparkling amethyst crystals glides through a track suspended in space. Each train car glows faintly, leaving a trail of violet stardust in its wake. The passengers inside appear as silhouettes against the glowing walls, their outlines refracting like prisms. Below, a massive purple planet looms, its surface shimmering with crystalline formations.
