A lone astronaut stands on the surface of an alien planet at dusk

A lone astronaut stands on the surface of an alien planet at dusk. The sky is a deep shade of purple, with swirling clouds illuminated by the light of two moons. The ground is covered in strange, bioluminescent plants that cast an eerie glow. In the distance, a towering, ancient structure, half-buried in the ground, emits a faint, pulsating light. The astronaut reaches out to touch the plants, unsure if they are friend or foe, as a sense of both wonder and dread fills the air.
