(for my private megaverse) was under Occupation of The Argonite Dictatorate, their home planet to be exact, a simple rebellion allowed them to not only push them off their homeworld , but to also allow them to start expanding outwards to the stars, liberating many worlds, they created eternalism after they have liberated the last world of the argonite dictatorate... they are highly advanced and unknown... they have entered and exited CBU many times, their striders and gunships as well as allies makes them look like a friendly version of the universal union from half life
