Zeus was quietly assessing the crowd. Even in a perfectly tailored smoke colored suit with a tie in an antique gold color and his cracked white & gold mask. He liked the cracked white alabaster look and since wearing a white suit would have been beyond gauche... gray it was. Even so, he was watching the crowd, glass of scotch in his hand and just taking everything in.
He was curious. Mostly as to whom might be whom at such an event, though some attendees were painfully obvious if not from their physical stature or attributes alone, then by how they dressed. Clearly, by height and build alone, the man heading toward the bar in company of a woman and another man... was Kratos with his mother and brother. Nyx and Erebos, of course, were dancing. Thor was... well, about as clever as Zeus expected from any Nord at this point.
There were others to figure out, and Hera would either already be here and was just mingling about somewhere -just happening to evade his gaze by matters of timing.
What Zeus was wondering, was if anyone -or groups of ones, were potential problems. It was not his event and not his problem, technically. But, he had children, grandchildren... subjects here and if the Underworlder's somehow managed to let things to go pot, he was going to have to be ready to take care of he and his. Not that he would have expressed that concern to Styx's children, who he was letting do what they wanted... he would have had to fight Styx on the issue since their grandparents were hosting and not only was Styx somewhat terrifying... So was Nyx. The latter moreso in some ways.
Not that he would ever say that out loud. To anyone. So, for the moment, he was observing.
