"Concrete? No. My suspicion is based on experience. It may not be entirely xenostech, just.. modified, or integrated. The Imperium is capable of making synskin bodygloves, and adding wings and glide systems to them wouldn't be that hard, but the more you put into the suit the bigger and bulkier it gets and the more power you need to run it, and the shots that I've seen have too slim a profile for that to be the case. There is at least one species I know of, however, that excels at miniaturisation. Jokaero. If you've run across a digital weapon, you've likely encountered an example of their work."
