When the night fell, so too did the temperature.
The alien planet with an average temperature of minus fifty-five degrees Celsius could plummet to a numbing minus 133 degrees Celsius in winter, while reaching a high of 27 degrees Celsius in summer.
The daily temperature fluctuations were not that extreme, but they still exceeded the limits human beings could withstand.
A malfunction in the temperature regulation system of their protective suits could just as well result in death.
The imperial apes, superior to humans in physical prowess, still possessed beast-like bodies despite their intelligence.
They were like apes on Azure Star, freely navigating the icy and snowy wilderness without a stitch of clothing.
This was one reason why humans referred to them as apes, even though there was a distinct difference between their appearance and built, and that of actual apes.
Dressed in simple protective gear, they could survive and even thrive in subzero temperatures.
