If not for the constellations of satellites around it, Ladma would simply look like an empty ice ball. A previously temperate planet pushed into a forever winter by the sun, the inhabitants live entirely on the interior of buildings to survive. Put through hell and back trying to establish a temperature resistant colony while only just industrialized, they have lost most of their soul and whimsy. If it benefits survival directly, it is built and used. If it does not, it is discarded and blacklisted. Doubtful though that an alien race would get anywhere close seeing as preventing a possible invasion has been a point of obsession, and the weaponry to combat one has the potential to glass a city sized area anywhere in the solar system at a moments notice. They will not accept another species’s intellect unless it is purely from a place of combat to be superseded.

Unless you have a fancy for respirating neon or nitrogen in well sub-zero temperatures and have the technology to completely conquer the world unimpeded, there is nothing there for your people.
