Guild Wars 2 Giveaway: Trivia #16

Hi folks, we're starting Quest 6 with an easy one and we really hope you're enjoying this. Anyway, today we want you to tell us two things. At what point (which episode) did we stop going on our own and joined a military order? Which episode was it and what was the name of that group? If you need help, here is a hint for you. Good luck!
