Under Da Sea
Atlantis was never a far trip, not if she was swimming full out.  Sure, she could have arranged for pick-up of some kind, as befitted a princess, but Marrina was occasionally about establishing her own independence.  She knew she'd been given incredibly free range in terms of royal demands on her, with her education in matters of state taking place on the side and sliding into her own schedule...

She wondered if all that was finally catching up with her.

In no time at all, however, she was at Atlantis.
