If before some people weren't paying attention to Aster's group, that changed after that little interaction between them and one of the many groups that descended from spaceships which were floating above the stage.
But soon the topic changed from that friction episode, to something along the lines of "where do these beauties come from", while not everyone had high backgrounds, there were people which came from the ruler families of their respective star clusters.
In other words, all the talented people from the while stellar system gathered here, and had heard or knew each other to some extent, that's why such an… "eye catching" group like Aster's, couldn't go unnoticed.
"Silence".
