Xeno means alien or foreigner, the imperium are highly Xenophobic. Xenophobia is a fear of people or other things like food from a different country or in this case: aliens. It's seems odd to me that a word from an old language would be known in a time where such things like Ancient Greece for example would be forgotten.
