Duke of Weselton

"Sorcery! I knew there was something dubious going on here!”"

- The Duke of Weselton upon discovering Elsa's ice powers at the coronation. "What the Duke of Weselton lacks in stature, he makes up for in arrogance and showboating. He's determined to get close to the the new queen - that is, until Elsa's magical secret to control snow and ice is revealed. He's the first to call her a monster and try to turn her own kingdom against her - anything that might help him exploit Arendelle's tradable goods."
