Life wasn't always high-speed. Even as a high ranking Galra soldier, one of three right-hands of the Emperor-to-be, there was still downtime.
Between battles and meetings and training hours, Acxa had time more or less to herself. Things like meal times, sleep hours, lulls in activity, those were all open hours to do with what she will. Maybe it was the exhaustion hitting her after a long work day and general stressful conditions, maybe it was simply her personality, maybe it's a mix of both, but she never found herself too much in common areas during her downtime. Occasionally, she'd mingle, she'd talk to Ezor or Zethrid more often than she did with random soldiers she was technically the boss of. But a lot of the time, she found herself just needing a breather, her own air.
And what else was a personal office and quarters for? It wasn't very spacious or incredibly furnished—understandably so, there was hardly much room for luxury for those less than royal when on a space battleship—but it was room for one and company and it had a door that closed. Her hands twitched to do the paperwork that sat on her desk, not due for a while but it was always her instinct to get things done. She ignored the impulse, far too tired to work but even relaxation took discipline for her. Her head tipped back onto the backrest of her chair, foot slightly propped up on the bottom drawer of her desk, forearms on the armrests. Her thoughts were just as quiet as they were loud, not really looking at anything in particular, functions slowed to an almost sleep-state in her minutes of very much welcome limbo.
But it never lasted, not really. After a knock, her office door slid open and she had to turn her head back across the room, arms falling into her lap and foot adjusting to a more professional placement on the ground.
