Correct me if I m wrong (it is why I post here to ask anyway), but when you were doing the Dragoon story line. that captain seem to point out something about only one person will become dragoon in each generation? and he point out how this time, because his original pupil betrayed him, that was why it is exception to have two dragoon this time. (somehow?)

Well, I m not so clear on dragoon story, so if anybody could point it out, it would be nice. Just that it seem to me that the lore telling about how there should be just one dragoon. now then I see trailer in 3.0 has an army of dragoons...
