The Notaries Guild oversees a vast range of services relating to the written word. In addition to its vital work producing legal documents and authenticating letters of credit, the guild licenses cartographers, bookbinders, and scribes, including those whose specialty is copying magic scrolls. Sivis bookkeepers work with numbers as well as words, and guild appraisers are trained to spot all manner of forgeries. One of the more interesting branches of the guild is the Hidden Word. This arm of the house sells both codes and codebreaking services, along with magical tools such as secret page and illusory script.

A number of smaller branches within the Notaries Guild handle specialized work: Aureon’s Press is the primary source of arcane ritual scrolls in the Five Nations, and the Hidden Word is a division that works on cryptography and code-breaking techniques.
