Milliways: the bar at the end of the universe. It's a bit crowded today, with a group of brightly-colored lizard people taking up several of the tables in the main bar and a more usual assortment of patrons scattered densely around the rest of the room - well, except for by the fireplace, where one patron is being given a somewhat conspicuous amount of space - perhaps it's the intimidating all-black outfit, or the way she's muttering to herself as she reads from the book she's holding, or the almost feral way she looks up when anyone in her field of view moves too quickly, but no one seems to want to get especially close to her.
Bar dislikes to straight up giving them catalogues but is willing to give magazine reviews about spaceships that do the trick.
DZ has a pretty good idea of what Deskyl will need - a meditation room and a sparring chamber and at least one workshop; the hydroponics bay can be small and should probably be automated if that's easy enough; doesn't need much of a sound system but what it does have should be very clear, or just go with visual displays, those are probably better; any vital or hard-to-fix equipment that runs along the hallways should go in the floor or ceiling, not the walls, or be shielded if it has to go in the walls for some reason...
Felix is taking notes. He can shield both horizontal and vertical surfaces. Why the vital equipment can't go on the walls?
"-Oh, sorry, sir, I hadn't realized you wouldn't know about lightsabers. Only Force-sensitive people can use them and they can cut through nearly anything."
"Ah. Well, the closest thing this ship has to a budget is a constraint on how much volume I could create given time and I could create a space-citadel if she so preferred. Could even do it in addition to the spaceship if she think it's convenient."
"All right." She doesn't know what the state of the art in lightsaber-proof materials is offhand, but with a little help from Bar, she can find out.
With a couple different layout options and choices for this or that to be slightly better at this or that expense, because if it's just presented as a completed plan that won't work either. DZ brings the plans back over to where the Sith is still sitting.
While she does that Felix is approached by a nearly-identical man with white-gray wings.
After perhaps fifteen minutes, they're done; the Sith doesn't scan the room, but looks right to Felix.
"Uh, hi again. This is my brother Fenris. According to him, we can essentially retain access to other worlds even if leave Milliways, do you prefer to retain access to yours?"
It helps, when he lands, but she's still keyed up, watching him carefully; she doesn't seem to notice the question.
That seems to be more confusing than anything else, but she does calm down once he's gone.
"Do you want to be able to go home again, Ma'am?"
"...maybe. Effects?"
"We would use a bit of pocket dimension to connect the two worlds. We would be able to control transit between the two worlds. Eventually we would like to fix your world's problems."
She gives him an assessing look. "Complicated. And - chance of trouble, for you. Sith're sneaky."
