Re: REGINA/NYX.
That's not the part I'm worried about. Between me and Noctis we'd be fine I think? Probably sleep for a week but fine.
Easiest way I can think to explain it is like a giant zipline. You can travel across it from the top to the bottom but only if you have someone to push you in the first place. I don't know if I could push myself across it. Maybe I could push everyone else, but then no one's left to push me.
