So when her engineer does not calm down, and still flinches every time she walks by - well, she finds a replacement, and she decides to transfer him to a place where he does not have to be near a Sith Lord. She has her translation droid, N-V09, nicknamed Envee, conversationally ask him where he'd like to live. Because if she asked he'd whimper out how he's happy where he is, and that's not the honest answer she wants. He turns out to have friends on Balmorra, and quite mysteriously, Callida learns of an open position on Balmorra and sends him a message asking if he would be willing to serve Darth Occlus from there. As it happens, he does, though he prefaces the reply with lots of I'll stay if you still have need of me, my lord, just say the word and I'm your man. She snorts and transfers him.
The astromech droid she picked up on Narr Shaddaa is quite happy with its new status as her ship's engineer, and is much less terrified of her. It rolls up to her near immediately, and beeps, Callida == buy new set of hydrospanners // TN-R13 == hate current set // TN-R13 == unable to do job and is perfectly happy to lead her to the exact set of hydrospanners that it would like. And then it beeps at her the next day, asking for a chassis upgrade and a set of wheels with more traction. Callida considers this a job well done, and upgrades the droid.
She wonders if she's going to end up replacing her entire crew with a legion of loyal droids that are just thankful she treats them in the same category as people. ... She might, though her pilot and doctor both seem perfectly happy to work with her. She'll see about defenses against ion based weaponry, just in case.
But ion weaponry isn't likely to crop up in the tomb that she's been asked to clear out for the archaeologists, so she tables that search for now. Droids as a rule, do better in Sith tombs than organic life, but they don't escape unscathed from the dark aura that tends to permeate the tombs of Sith. They'll stay on the ship, she'll walk in and kill any creatures living inside, dispell any ghosts that still haunt the premises, and disable any traps, and then she'll estimate how long anyone that isn't a Force-sensitive could stay in the tomb without their minds being twisted, and go from there.
Clearing out the tomb might take a few days, so she's packed for them. Ration bars, canteens, water purification tablets, and other such necessities. If she runs out of supplies she can always retreat back outside, but she'd like to get the tomb cleared out in one trip.
Unfortunately for her, she barely even makes it past the threshold before the scenery abruptly changes, and the oppressive feeling of the dark side dissipates. Instead of a dark tomb, she's in a forest of some kind.
She frowns, and begins carefully searching her new environment. This tomb just got a lot more interesting.
There is another winged person in the house. She's in a side room, with a book; she looks up when the door opens, sees Callida, her eyes go wide with horror and hope at the same time.
"He has my name; you fed him; that means that you're his master and he's mine. If he'd fed you instead he'd have you too. I would've been allowed to talk as soon as it wouldn't be interfering with a capture attempt and we could have maybe gotten away by cooperating because he's not very smart, but this is better. You can tell him to do whatever you want."
"Right, okay. Thank you. Uh, Yellow, always tell me the truth, and tell me in an obvious way if Promise lies to me, or has lied to me since she started talking." She looks back at Promise. "High stakes, paranoia, I'm not a monster but I need to be sure I won't have a master, I hope you understand."
"Ordering him to give you a specific order that we work out beforehand, to make sure that you're not lying about that specific thing, and then clearing all of your orders again. He's an awful person, but I just met you ten minutes ago, I don't know what would happen five minutes after I left when you're free to tell him to jump off a cliff, or gouge his own eyes out. I'd fall in your favor in the 'which one of you is allowed to give the other orders' game, but I'd rather not play it at all if it's going to lead to a worse situation than what I've already got in front of me."
"I could think of situations that could come up where I'd need a vassal - or where I'd need a master - and then I'd come get Yellow sooner than find someone else, but I'm not in such a situation now and don't plan to get entangled in one if I can avoid it. You can have Yellow order me not to lie to you for a minute."
"Travelling from planet to planet takes time. Sometimes not very much time, but some. And travelling distances on planets takes time, too. So you could transfer objects or people from one place to another faster, which would be good for things that can't be moved except under very specific conditions, or things that are ruined after a certain amount of time - so on."
