Episode One: New Taste

It's hard to see whether Flitter is being literal, metaphorical, or something else entirely. Still, you can use deductive reasoning to assume these "bad men" are the same gang you encountered down below.

Trying to piece together Flitter's physiology is a challenge in itself: it's like staring into a black hole, but occasionally you get a small glimpse of a thin white line moving underneath the jacket.

It's hard to see whether Flitter is being literal, metaphorical, or simply insane. Still, you can use deductive reasoning to understand two things: these "bad men" are the same gang you encountered down below, and the "star" seems to be a rather powerful item.

The cameras don't give you anything particularly interesting, just the members working tirelessly.

Flitter spends the duration looking out the window, seemingly admiring the city.
"We told you, the bad men! So hairy and ugly too! They laugh at us because we are small, but they are just too large." She shakes her head, looking unhappy.
She tilts her head, hair falling to the side as she thinks. "Hmmm...no. But we are happy to meet you." She nods confidently.

During this exchange Rodrigo doesn't detect any malicious intent from Flitter.

Before you know it the two of you (plus anyone else who decides to join you) and Flitter are situated in one of the vacant medical rooms. It's modeled after a common examination room one could find at any hospital, albeit with much more interesting tech. There are various instruments for X-rays, magic detection, eyesight, and more at your disposal. Flitter patiently sits on the counter, adamantly wanting to keep the coat on throughout the process.

Spidermoon's efforts to comprehend Flitter reveal: They have roughly the same organs as a human or elf, full set of bones, blood, and is positively brimming with magical energy. The exact nature of this energy is a mystery however, as the equipment goes on the fritz whenever you try to get a reading.

Prowl's search comes up empty, trying again and again to match her characteristics with any known creature. The only solid info he obtains: Flitter is definitely not a common race (halfling, kobold, goliath, etc.) in disguise.

"Yes! We wish to 'thrash' them, to see them squirm!" Flitter practically shouts, her eyes squinting in anger at the mention. These feelings of rage pass on as she calms down. "The b...build-ing? We do not know. Walls were all around us, and a... scary room too. Strange magicks, sinister voices! That's where Star is, We can feel it's presence longing for us. It is so dark down there, cramped, like the void itself! But even void cannot contain Us, small cracks and holes to slip through lead us to damp halls. So so noisy, but safe. Bad men do not chase, and we ascend to find you."

Pouring through your monolithic number of tomes and computer-based search indexes proves just as tricky. Best you can tell is she has ties to denizens of Dal Quor. Which race exactly is beyond you.
