You gave me the answer that I was looking for, which is someone working on the lights. It is fine, maybe the rank might be a little lower for maintaining lights because don't forget the crew of the ship also do that. The other stuff I do not really care about, I just wanted the reason/for it to be reasonable.  [@ClocktowerEchos] 

But aside from that, I think it's fine, maybe she is based from the ship if she is helping maintain it.
