While at another masquerade ball, which's your task for today as an assassin, find and kill a thief. While standing at the buffet table, listening to the pesky vultures who were trying to ask you to dance, you notice a red-haired man with a fan covering half of his mask. You could swear he was staring straight into your soul. When you made eye contact, the man waved his fan in a characteristic way and then left. Then it dawned on you that it was a simple fan language You followed him.
