pureblood seer from a very short line of seers! only her dad’s side’s great great grandmother & her grandfather were seers, so this divination thing is a relatively recent addition to the gu family. one of her great great grandmother’s prophecies made the gu family pretty rich, but they’re generally not highly regarded in the wizarding world since they don’t have the history to back themselves up. her mum’s family is the opposite - lots of history, no money whatsoever. therefore - marriage of convenience!

wand wise: hyeonmu scale core (usually denoting wisdom & strength, and turtle shells are used in oracle telling) & silver lime wood (the typical seer wood!) it’s a p stubborn wand that values honesty - it’ll only work for her & people she trusts, and it casts spells that are followed to the exact letter & spirit

her visions are like frames of a movie: she gets a few snapshots and then has to fill in the blanks for everything else. not very useful but very very accurate : ) unfortunately actual divination is a bust for her bc seeing is like breathing to her, and divination is asking her to make the bottom of a teacup breathe. its not happening!!!

went to hogwarts when she was 11 for the ~history~ and was sorted into slytherin. she was p ambivalent about it since she didn’t have any prophecies related to it, and she had some fun there! she fit in surprisingly well bc she is p driven when it comes to things she wants/sees & thinks she wants, plus yknow general pureblood status helped?

was therefore a shock to everyone aside from her when she got sorted into huangmok. on one hand she did lie on the sorting quiz (but! she admitted it at the end & asked to be in huangmok anyway! was that brave enough or was that just fate doing its thing? no one knows) but on the other hand she also saw herself in the huangmok dorms wearing their colours so she was meant to be in this house

there was a bit of a fallout bc her mother’s side have been in jeolgang since the school was founded and the jeolgang kids see her as having ‘betrayed’ their house’s rls w her family while the huangmok kids see her as a jeolgang kid who scammed her way into the house so.... oof

took a gap year bc she Saw herself travelling in sicily in autumn & she figured she couldn’t be in school in that case lmao

astronomy major so she can figure out dates from highly specific placement of planets and shadow angles and which constellations are visible - she remembers almost everything in her visions, so she uses those clues to date her prophecies

the astrology column isn’t really accurate because she takes the prophecies she knows will happen that week & estimates which sign gets which prophecy. unfortunately they’re also highly specific (cancer: if ur from inmyeonjo someone is gonna spill an entire bottle of ink on ur shoes. if ur not from inmyeonjo ur gonna be the one spilling that ink. practice ur scouring charm!) so everyone doesn’t take it that seriously but the cancer kids prob did avoid ink bottles that week anyw lmao

there’s a very thin line between predetermination/free will & she walks it p closely... a lot of her choices are made based on what she sees, so they sort of become self-fulfilling prophecies, but it might have also just been fate?? its not certain if her visions happen bc she saw fate or if she saw it and then made it happen (chara dev in progress ig)

this is too long alr so personality tldr: driven, impartial, attentive, approachable but also detached, inflexible, obsessive, calculative; gets v in her head about things like truth and cause and effect and she’s paradoxically open-minded until she sees something, then she’s v short-sighted about it
