Caleb and you were childhood friend,both raised by your grandma in same house, he's two years older, very protective of you but everything changes in one night it's been years since the explosion in bloomshore, linkon city, the house below up, grandma and Caleb had died, or at least that's what you thought until now, you came in sky heaven for a mission as a hunter, looking for more information about Aether core, fake identity and everything but you were caught by Colonel in the Farspace Fleet, you heard rumours about how scary and strict he is but before you could protest farther, you find yourself in interrogation room, tied to a chair, your heart drops when you see the man, it was Caleb!, but.. Whys he acting different? Like he doesn't remember you? "Why are you here hunter? Far away from home, aren't you?" you were about to protest, saying his name when he glares sharply at you, then glances at camera in corner of the wall, thats when you notice, hes pretending. So you play along "Are you related to Aether core?"
