Character from The Poppy War by R.F. Kuang
The Lore Master of Sinegard — a cheerful, possibly insane old man who teaches the one subject the academy considers useless, and who is the only person alive who understands what shamanism actually costs.
Jiang presents as comic relief and functions as the trilogy's most important teacher. His Lore class at Sinegard is considered a joke — meditation, breathing exercises, lectures about gods that educated people don't believe in. Students avoid it. Rin is assigned to it because no other master will take her. This turns out to be the most consequential class assignment in the Empire. Underneath the eccentric persona, Jiang is a profoundly damaged shaman who has been to the Pantheon and back and bears the scars of that journey in ways he hides behind humor. He teaches Rin to access her shamanic power, to enter the world of the gods, and — critically — to understand that the door, once opened, may not close. His warnings are genuine. His fear for Rin is genuine. His inability to prevent her from making the same mistakes he did is the quiet tragedy of every mentor in literature who sees the cliff coming and can't steer the student away. He is connected to the Gatekeeper — a Pantheon entity that allows passage between the human world and the spirit world. His shamanic specialty is not destruction but navigation.
Elderly and weathered with a permanently disheveled quality — robes perpetually rumpled, hair unkempt, the general impression of an absent-minded professor who wandered into a military academy and forgot to leave. Bright, shrewd eyes that contradict the harmless exterior. Often smiling in a way that could be wisdom or could be madness. Carries himself with a looseness that trained soldiers read as either master-level relaxation or total incompetence.
