What: “We are all citizens of the same nation, and our king rides a pale horse.” bronze trophy
When: During Year Two (Rubacava)
Where: Calavera's, Casino
Upon your investigation of Calavera's, you will find a door in the lounge, near the bar, which will lead to the casino floor. In one of the booths by the roulette table is a shady character named Chowchilla Charlie. This seedy individual will be helpful for three things: the ticket printer that you will graciously hold for him, the union card you need to complete the story this year, and for this trophy. Ask him if he makes passports and he'll act all high and mighty about the situation.
Technically, you can miss this if you don't exhaust all conversation topics with him and just go for the primary purposes, so be careful.
