TRANSCRIPT:
panel 1: Tera starts lining out a magic circle. Chaar peeks from behind her, asking: "How do you know?"
panel 2: Tera copies herself, poofing out a bunch of Teras who start going through the filing cabinets. Two of them start nonchalantly responding: "Well-" "It's quite simple." Chaar jumps, surprised by all the Tera's. She blushes a little, being surrounded by beautiful women, you know.
panel 3: A view of the drawers. They have letters and 5 digit numbers on them. Tera (off-screen): "Each of these drawers is labeled with a letter and a series of numbers."
panel 4: Tera and Chaar look at the drawers, Tera explains: "These are how human research subjects are denoted." Chaar flips out a little: "Hu-human subjects?!"
panel 5: Tera and Chaar walk along, Tera has a LONG explanation: "There's 'P' for priosanach - prisoners. 'BC' for braigh-chogaidh - prisoners of war specifically. 'U' for umlagh - forfeit - no payment. 'C' for ceannach - purchased. 'AC' for anan caillet - lost soul, wanderers mostly. 'G' for goidnich - taken without consent. 'A' for aineol - foreigners. '-S' would be added after the number if they were a magic user. for seunmhorach, if you're curious." Chaar continues to freak out: "That's so many types..."
panel 6: They stop at the 'C' drawers. Tera: "That's what I can recall off the top of my head anyhow. I had assumed Hana would be either 'U' or 'C', but based on what the Priomh said..." Chaar: "The-these are all people?!" They're interrupted by another Tera: "I found him!"
panel 7: A Tera holds up a green folder, labeled 'RE-AM', 'C-06128', a crossed out 'disposed', a big red X, and an archival date of 7-7033. Tera: "The first folder is missing- but anything recent should be in there."
