The Nedes (more commonly known as Nedic peoples) were a race of men who were widespread in Tamriel until the First Era, when they were absorbed into the bloodlines of the modern human races. Their characteristics and ancestry are unknown because of conflicting historical accounts and definitions of the word, but modern-day Cyrodils (especially the Nibenese) are known to be their closest relatives. The true story of their origins became lost and confused during Tamriel's violent past, and is now a subject of debate among students of history. Efforts to interpret surviving records have given rise to several schools of thought, and some explanation is needed to separate fact from the overlooked details and possible propaganda of official accounts.

Sorry for the small amount of writing but I couldn't find much else on the Nedes.
