expanding further on Wei Wuxian’s arcane verse && his presentation as a fox spirit, specifically he is what’s known in Chinese Mythology as a 狐狸精, or húlijīng, roughly translated into fox spirit in English. hulijing are shape shifters and, depending on their presentation, can be considered either good or bad omens. due to Wei Wuxian’s upbringing and his general nature in the Arcane verse, he is considered a bad omen, and unless you’re someone he trusts or has willingly transformed into his fox form in front of, if you see the spirit of a black-furred fox, it typically means your death is coming.
it’s important to keep in mind that when doing business in The Green Light District, Wei Wuxian will almost always be either shrouded in magic or wearing painted fox mask, keeping his appearance and identity ambiguous. the only time you should be concerned for your life is if he presents himself in his fox form when talking to you, or completely shows his face. this typically means that he has no intention of letting you leave alive.
he is a businessman, yes. he runs The Green Light District with the exiled remnants of the Wen sect as a means for them to live peacefully; but he is also capable of being playful, conniving, thrifty, and devious. there are rumors of a fox luring unsuspecting passerbys to their doom if they get too close to the district without a proper token for entry, and this rumor is true. sometimes he simply likes to play tricks on others and thoroughly enjoys watching his victims suffer. however, his victims are never innocent people and are almost always criminals or person with ill intention. Wei Wuxian does not kill without good reason. he very well could’ve devolved down such a path, being a Vastayan who was rejected by topside and scorned in Zaun, but he chooses to keep some of his good will and mess around with only those who deserve it.
