In the distance on Diviot's seemingly uninhabited alien planet stands a lighthouse.
Diviot whisks Kai and Damon to an alien planet for some private time to drain their Power Ranger energies. The other Rangers quickly find them; so, presumably, the planet isn't terribly far away. If Terra Venture's goal is to colonize a new world, it seems rather inept at spotting one - especially one with at least one ocean - as they come into its vicinity.
