Technically speaking all beings that do not originate from your point of origin are aliens. As I could define 'Earth', my point of origin, as being this particular version of Earth, that would cause all characters within this roleplay to automatically fall under the category of 'alien'.

But hey, that's semantics. Sorry, couldn't remember what you originally called them so I just went with aliens. Because the Ethereal seemed to be in charge and your foot soldiers seemed to be alien foot soldiers.
