After Arthur's speech, the grand auditorium was transformed into a party hall courtesy of Layla's Authority of Creation. As such, what had initially been a gathering for a public address gradually became something more akin to an afternoon party, where the godslayers could mingle with one another and, more importantly, have the opportunity to interact with their new Grand Commander.
It was essentially a 'get to know each other' occasion, allowing Arthur to become more familiar with the leading figures of the godslayer society while also giving them the opportunity to personally learn more about him beyond what they'd been taught throughout the centuries.
Like so, Arthur spent the next few hours moving around the various groups of godslayers, engaging in conversations and getting to know the people who'd been entrusted with overseeing the affairs of the new race across the different planets.
