The Aesiran are generally a larger race of humanity, with the examples we have seen tending to average far heavier and more massive than Earthborn humans. They are not as large as the Roderan, but are well outside the human normal otherwise. They also prefer colder climates outside the general definition of livability by most humans, but can operate in most normal environments. They are culturally carnivorous, and most of their food revolves around fish of some kind or another. Even their warships leave home with living fish in their water bunkers so they can eat fresh food no matter how far they travel. It is with great honor that they to give you fish from their own bunkers. They expect you to eat it and enjoy it.
