A reasonable approach to security. And the purple?

Merrily replaces her towels and wheels his cart out.

Creepy.

She checks with DZ to make sure there's nothing she needs to know first, and goes to knock on the eager peoples' door.

They were expecting to be summoned by computer message but this way works too! They are blue and green and yellow including Mosha.

"Hello!" says a blue.

Deskyl steps aside to let DZ into the room. "Hello," the droid replies.

"Is the hotel room working all right for you? We can set up something else if you'd prefer." Their room has a floorplan like hers but they've got it set up with carrels and chairs and no beds.

"It's been fine, thank you." She follows Deskyl to the chairs and sits next to her.

"We're more excited than we can say about the prospect of faster-than-light travel, but since Deskyl's recuperating it can wait on her feeling better if that would be easier. In the meantime we'd love to know more about the civilization you're from and how you came to be here."

"Of course." She signs to her companion, and then launches into an explanation.

The civilization they're from is a sprawling one; it's hard to get a comprehensive survey, but there are millions of inhabited planets, possibly tens of millions. Most of them are quite a bit less densely populated than Amenta; humans - the dominant species in most places; Deskyl is one - don't spring and have a much lower reproductive drive than Amentans do, so population pressure is much less of a concern. Humans also don't have castes, and seem to inherit fewer traits in general, but otherwise are very much like Amentans; this isn't surprising, there are hundreds of known sentient species and many of them are fairly similar to humans. Tech-wise they have spaceships of various kinds, space stations, droids of various kinds, high-quality prosthetics, and so on.

Sith - the closest concept in Tapap is 'wizards', but it isn't very close - are a rare subset of humans and some other species, who can do things that are essentially magic; telekinesis, physical enhancement, sensory powers, and minor mental effects are all common abilities for them.  Deskyl is a Sith - she pauses to ask Deskyl for a demonstration of the telekinesis, which she gives, sending a pen tumbling in midair around the room - and she teleported them here when she was attacked by another Sith. Teleportation isn't something Sith can usually do; now that she's done it once, she may be able to figure out how to do it again, but that isn't very likely.

Everyone is fascinated.

"And you're her interpreter? Is that a common role for robots?"

"More like a personal assistant, which isn't very common; my line is intended as general-purpose servants, though, so it's not very different. And protocol robots are commonly used for translation, particularly in diplomatic contexts."

"What other castes of robot are there?"

"There are five - we don't go by color; the classes are numbered instead. The first class is uncommon and does relatively pure science; math and astronomy and biology. Medical robots are also considered class one. Class two robots do applied science - maintenance of other machines, terraforming, engineering work, and so on. Class three robots are intended to interact with humans and other biological species; servants and protocol droids are the most common, but there are also lines that are made for tutoring or childcare or other similar tasks. Class four robots are fighters, and class five are built for unskilled labor or very specific tasks, like handling dangerous substances."

Attentive eager nodding. "It'd be incredibly useful to us to be able to build robots here."

DZ signs to Deskyl; the woman sits up a little straighter and watches the assembled group more closely.

"We're a little concerned about that, actually." (She signs along as she speaks, now.) "Humans don't generally have much trouble finding different work if their jobs are taken over by robots; Amentans seem less flexible that way."

"Purples have been declining as a share of the population for many generations as fewer people are needed as farmers and so on, but we know how to keep it smooth and not crash the economy in the process."

"That still seems unpleasant for them. And we're especially concerned about the reds."

Amentans blink, nonplussed. "- you are?"

"Yes. They are people; several of Deskyl's powers let her be sure of that."

"Oh, we don't mean to say they - obviously they're members of our species."

"I mean that they're not different from you in any way that affects how you should treat them."

    (Should I be killing someone? Deskyl signs.

Not in particular, she signs back.)

(Greens are interested in that there sign language.)

"There've occasionally been suggestions that they could be phased out gently with a pension."

"That doesn't sound like something that they'd be satisfied with, any more than any other caste would be."

"Apparently humans solve this problem by not having a caste system, but that's really not feasible for Amenta."
