Vale of Wolves
Lore is the a term used in the Chancery to refer to all knowledge without a directly practical application. Many learn fundamental snippets of Lore from a Chapel school- the trivium of Logic, Rhetoric and Grammar, the basics of Refinement and the Epigrams of The Prophet, as well as the lives of the Primarchs- especially those with a local following and those who sponsor trades or activities close to a refined heart.
Other knowledge is common enough, even though informally taught. The etiquette of Merchants and Lords is understood even amongst artisans- or at least the means to avoid offending them is. The disposition of the Refined Races within the Vale of Wolves, and more importantly that of the Unrefined, is well known, as well as the character of various locations therein and their relationships.
More esoteric is the knowledge of The Worlds beyond the Vale, along with the High Gods that ruled in ancient days and the Low Gods that challenged them in the period leading up to the Chaos Plague. Such knowledge is seen as akin to an interest in the Occult Traditions, practices likely to raise suspicions with Witch Hunters and Nobles alike.
