Everyone knows that there are four hunter academies in Remnant right? Well, that's not entirely true. You see there are acutely five hunter academies in remnant, Shade, Beacon, Haven, Atlas academy, and Bastion. Never heard of Bastion? For a good reason. You never, under any and all circumstances want to go there. But that's just where a reaper and a knight are sentenced to die.
