That depends. If you're talking about a wesen that resembles an alien, like the Glühenvolk, then the answer is no. If you mean a wesen that left the planet and returns, then your on the edge. A wesen that ddeveloped independantly from Earth wesen on a different planet would probably not work. The final idea is that aliens would be classified as non-wesen beings.
