Knowledge

Overview
Characters possess a variety of attributes. There are the actual Attributes, magical aptitudes and skill, and more. Knowledge is a special mechanic relating to Language, Culture, and History. Knowing a language in common improves Diplomacy. Knowledge of another culture has the same effect. However while characters can know multiple languages they only have one culture so its a strong boost but a more narrow one. Knowledge can also improve the happiness of populations. Knowledge is stored in Books assuming a character chooses to write one.

History is important to know for opinion bonuses but it also affects the event system. Language has an effect as well as it allows for reading foreign books or inscriptions in ruins. Ancient threats can often be countered by using a knowledge of history and language to locate ancient artifacts, free imprisoned spirits or mages, or other methods.
