The Roderan are a famously stoic and dour race. Cold both in appearance and temperament. Native to worlds far colder than Earth, their blood shares many properties with anti-freeze, and its effects saturate throughout their extremities. This translates into tolerances of temperatures far lower than most Earthborn humans can endure. They actually prefer air temperatures well below the freezing point of water, and become increasingly uncomfortable as that point is approached. It is perhaps no surprise that the Earthborn humans they prefer to deal with are those who live in cold climates. Luckily for humanity, there are many people who live where the air hurts our faces in winter. And some of us even claim to enjoy it.
