[@TheUnknowable] Glad you made such a flawless answer. To be honest I already knew you had the answers but I was just testing. But still one more point. Wouldn't prefabs be built, so they keep as much heat in as possible for effiency? That would emit heat below 3-4 Celsius which is easy to mask even at night. Or I shoulf ask the better question. What is the annual norm for temperature. Cause that gives a good idea about how hot or cold the nights are.
Also did military come with us? Or was it only settlers.

Edit: No matter the answer, I like the RP. Will make a CS when I have time. Just asking around for possible solutions in the future :D

It's a pretty cold planet which gets just above freezing most nights, but warms up during the daytime, at least where we are.  Prefabs would be well insulated, but once they saw the people they would be drawn to the area.  I suppose if you went inside before it got too cold you could escape the notice of most of them, but it would be pretty risky, as any leak in your insulation or residual heat could draw them to you.  The creatures live underground or in caves where it stays cool enough for them to live year-round.  They also live in pretty large groups (maybe a dozen for the larger species, several dozen for the smaller species) so one of them spotting you would lead to you being swarmed.
