The Edema Ruh are a travelling people - performers, musicians, storytellers, and entertainers who wander the roads of the Four Corners in family troupes. They are Kvothe's people, and his childhood among them shaped everything he became: his gift for music, his talent for performance and deception, his quick thinking, and his deep knowledge of stories and folklore. The Ruh are widely distrusted and looked down upon by settled society - dismissed as beggars, thieves, and vagabonds, subject to prejudice and sometimes violence wherever they travel. Kvothe carries a fierce pride in his Ruh heritage throughout the series, and insults to the Edema Ruh are among the few things guaranteed to provoke his anger. The Ruh's code - "one family" - emphasises absolute loyalty among their own. It was Kvothe's Ruh troupe that the Chandrian slaughtered, leaving him orphaned and alone on the streets of Tarbean as a child, an event that sets the entire story in motion.

The University is the foremost centre of learning in the Four Corners of Civilization, a sprawling institution where students study everything from medicine and mathematics to the arcane arts of sympathy, alchemy, and naming. Located near the town of Imre, the University attracts students from across the known world, though tuition is set individually for each student each term by the Masters - a system that makes Kvothe's perpetual lack of money a recurring source of tension. The University is divided into several disciplines, each overseen by one of the nine Masters: Rhetoric and Logic, Mathematics, Archives, Chemistry, Medicine, the Artificery, Sympathy, Naming, and Linguistics. Beyond the main University lies the Arcanum, the advanced programme for students who show true aptitude. The institution is also home to the Archives - a vast library that Kvothe both reveres and is periodically banned from - and the Fishery, where students craft magical devices called artifices for sale. For Kvothe, the University represents both his greatest ambition and his most persistent source of trouble.

The Arcanum is the advanced division of the University, the premier institution of higher learning in the Four Corners of Civilization. Students who pass the admissions interview are accepted into the University, but only those who demonstrate sufficient aptitude and knowledge are elevated to the Arcanum, where they study the deeper disciplines of sympathy, alchemy, artificing, naming, and other arts. Admission to the Arcanum is granted by the Masters - a council of nine who each oversee a different discipline - and requires passing a gruelling oral examination. Students within the Arcanum hold ranks from E'lir (the lowest) through Re'lar to El'the, with advancement dependent on demonstrating mastery to the Masters. Kvothe's desperate pursuit of admission to the Arcanum, and his turbulent career within it, drives much of the narrative of The Name of the Wind and The Wise Man's Fear. The institution is equal parts sanctuary and battleground for him - a place of genuine wonder and discovery shadowed by rivalries, politics, and chronic poverty.

The Adem are a reclusive warrior culture living in the harsh, wind-swept region of Ademre, far to the east of the civilised Four Corners. Their society is built around the Lethani - a philosophical concept that governs right action, somewhat analogous to a martial code of ethics but far more nuanced and difficult to articulate. The Adem are renowned as the finest fighters in the world, practising a system of hand-to-hand combat called the Ketan, and many earn their living as mercenaries - though they consider this a practical necessity rather than a calling. Their culture has several customs that outsiders find strange: they communicate emotion through subtle hand gestures rather than facial expression, considering open displays of feeling to be barbaric, and they hold unusual beliefs about the nature of parenthood. Kvothe trains among the Adem during The Wise Man's Fear, earning the right to carry a sword named Caesura - an achievement that few outsiders have ever managed. His time in Ademre fundamentally changes his fighting ability and gives him a deeper understanding of discipline and restraint.
