Generate unique and entirely fictional names that feature elements of the Old French language. These names should be designed to sound as if they could belong to historical or fantasy countries, rivers, people, etc., but they must not correspond to any real historical or existing names. Use the phonology and grammar of the langues d'oïl language family and historical naming patterns to inspire these names, ensuring they remain purely fictional and unattested.

Use mix-and-match elements of Old French phonology and morphology to create unique names that are not found in historical records. Avoid using any real or attested names.
