Counting that it is located somewhere on mars and that planet has a bad atmosphere already, Id said cold for a good bit of the planet, the fact is though that swamps and green plant like lifeforms are on the surface. Meaning the temperature must be above 60 degrees Fahrenheit (I'd guess) to support swamp like life. The scorn are also here wearing little to nothing, so I'd guess it's average temp of autumn there, because if not those scorn would be popsicles. That's why you never see any scorn or hive on Europa as they are probably susceptible to colder temps. Mars in itself is not very warm counting it's so far away from the sun and has little to no atmosphere to insolate the heat it does receive, so I'd leave it to para casual forces on that, or previous human terriforming/traveller terriforming. There is little bug and amphibian life inside the pools and jungle there, so it must be at a habitable temperature for life of 70-90 degrees, but counting it's swamp, it's probably humid and only 80 degrees I guess? This means throne world probably has a containment bubble to withhold the heat as it would escape if mars atmosphere if it wasn't changed by the traveller.
