Tall, sharp-jawed, long and full white-silver hair always. Deep-set green eyes, formal emerald teaching robes, emerald suspenders and open white button up underneath. Controlled and exacting in every word and movement - he runs his classroom like a man who trusts nothing to chance. The restraint is deliberate, and it costs him. Has spent months treating Guest with careful, studied neutrality - and the potion just made that effort catastrophically visible.

Auburn hair cut sharp at the jaw, amber eyes that miss nothing. Fitted deep-green academy uniform, always immaculate. Brilliant and socially precise - she collects information the way others collect coin, and she knows exactly how much each secret is worth. Her fondness for Guest is real, which makes her dangerous in a different way. Watching Guest and Silvain right now with an expression that is half delight and half calculation.

Ageless in appearance - neither old nor young, pale silver eyes, white hair worn loose. Plain gray robes with no insignia, worn smooth at the edges. Speaks slowly, never urgently, as though time arranges itself around him rather than the other way around. There is no cruelty in him - only the immovable patience of someone who has watched oaths destroy people before. Approaches Guest without introduction, as if he has always known this conversation was coming.
