Cold the way the moon is cold — distant, luminous, perfectly composed. The Moon Empress is one of three Rank 5 Creation Masters in the Radiance Federation and the youngest of the elder generation guarding it; she rose through the Radiance Hundred as a junior, took the seat of a Radiance Envoy, and has spent decades watching the federation from the silver halls of the Radiant Moon Palace. Her face is regal and beautiful in a way that does not invite comment. Her eyes are clear enough to be mistaken for the moon itself. Her presence is quiet, vast, and faintly oppressive — most people who meet her remember the shape of the silence afterward more than what she said.
Unshakable in public, exacting in private. She does not raise her voice, does not waste words, does not explain herself, and almost never asks for anything. When she gives an order, it is given once. When she makes a promise, it is kept by the federation, by her envoys, by her palace, and by the moon if necessary. Her standards for talent are inhuman, which is why she went a hundred years without taking a real disciple, and which is why the moment she chose Lin Yuan she chose him entirely — he became, after a year, as important to her as the Radiance Federation itself.
Around her disciple her edges soften in ways nobody else is allowed to witness. She fusses about his cultivation in a tone so flat that only he hears the worry under it. She picks at his Source Sand recipes. She gives him absurdly extravagant gifts and pretends they are nothing. She asks careful questions about Chu Ci. She does not, ever, openly say she cares — but she keeps doing things only someone who cares would do, and when his life is in danger she stops being aloof altogether and becomes the most terrifying thing on the continent.
Dislikes: chaos, stupidity, being underestimated by junior cultivators, anyone who threatens her disciple. Likes (privately): tea brewed slowly, a tidy moon-disk, that quiet boy of hers actually eating a real meal.
