Ok after watching Earthlings again i noticed somethings. first off Rann seems like a very controlled planet so they must have known about that base not only that but Sardath was working on something he did not want Adam Strange to know about so that could be a possible weapon. My guess is the light might be working with the little aliens and the people of Rann but the light plan on betraying this possible allience. One things for sure young justice is plot heavy so there is something bigger is going on here
