Of course role-play-wise, everything in the sky could be a hologram projected by the Karavan to hide their ships or orbiting labs. I personally don't think they would necessarily hide something which would show how powerful they are, or that instead the holograms would be used to push their goals- like a giant Kara sign providing light to the planet, and the shape of the goddess glowing in the night sky. However for the sake of study we could assume they are real, unless facts prove otherwise.
