Thomas had a deep hatred for the King and anything he threw but he knew that he had to attend to look good. Also it gave him the chance to meet knew people and form connections enhancing his power even further. That was the main reason he attended this things- and in the hope of convincing Anne that he was still her father. That was important to him. Esepcially since Vampires and Werewolves were unnatural... he hoped to bring her back to him.
What confused him though were the Portal's unusual activity of late. It hadn't brought this many new people here in a long time. Thomas couldn't help but think something was afoot with it all. That was another reason he was attending this Ball tonight.
Leaning against the wall with a drink in hand he watched everyone interact with one another trying to figure out who would be the best to get to know. Who would take him the furthest.
