As Elowin speaks about their goal, Eozindra watches the group of tieflings very closely. Aside from their random animalistic features, none of them are armed or hold themselves like experienced combatants. They had taken defensive postures that are only slowly relaxing. Of the various tiefling features, only the one dwarf's quills pose any kind of danger. Though Eozindra has seen tieflings exhibit supernatural charm and impressive magical effects in the past, she senses only fear and hope from these strangers...and a little bit of admiration. "...they're so clean!..." Lookout, the little tiefling, murmurs to the tiefling woman, Foca.
Elowin finishes what she is saying, and considers what she knows of tieflings and how they fit into Lunea's directives. As tieflings, their demonic heritage allows them to see in the dark even if their primary race cannot normally.
Ishi notices that none of them are armed; in fact, there don't seem to be any things that could be used as weapons in this squalid little camp made from scavenged materials.
Regina is visibly reassured by Eozindra's statement, but as she starts to respond she begins to hack and wheeze. "This is our home," Foca speaks up as Regina coughs. "We each came down here to live in peace, and not be abused or reviled as different or demonic. Histrik and Clutch have been down here longest; the rest of us have found this refuge since." She cocks her head, most of her wariness gone. Clutch, the big dragonborn tiefling, begins to cough as well. When it becomes clear that she won't take over the narrative, Foca continues. "Yours is not the usual reaction we get." She looks around, and then responds to Eozindra's assertions about her background and traveling companions. "We're glad for your sympathetic words, and you're welcome to pass through."
The others have been staring at the adventurers with admiration this whole time. His mouth moving faster than his brain, young tiefling Digger interjects: "They're all gorgeous!" As soon as the words are out of his mouth, he claps his hands over his mouth. Obviously blushing even in the dim light of the oil lamp, Digger attempts to cover his gaffe. "What I mean to say is that I offer my service to such beautiful ladies!" He makes a clumsy attempt at a courtly bow, and realizes that there are other people in the party (Ishi, Morik, and Adran in the back) than just Elowin, Elysia, and Eozindra, "...and their companions, of course." He remains there for a moment, and then realizes he doesn't know how long you are supposed to stay bowed. He straightens and says "I know the area pretty well. There's all kinds of ruins here; this part of the tunnels is very old. I would be delighted to provide any service you require, like...uh...well, showing you around, I mean. You just need to avoid the Lord Mayor's Men."
As far as you can tell, none of them even suspect that Elysia is right there, still invisible.
(Edited to account for the fact that Elysia is also visible)
