The Glenmoril Wyrd is a witch coven which once had a presence in High Rock, Hammerfell, Solstheim, Cyrodiil and Skyrim. The coven is notable for its ability to cure Lycanthropy and Vampirism. The witches have strong ties to Hircine. Many members of the coven are vampires who dwell within the cities of High Rock; this tribe of vampires grew so powerful as to gain the attention of the Cyrodiil Vampyrum Order, who considered them to be "Rivals". The witches are known to polymorph into enormous ravens, as well as wolves, and in time many became hagravens.

The Great House traditions derive from ancient Dunmer clans and tribes, but now function as political parties. In modern times, Morrowind is ruled by the Grand Council of five Great Houses: House Redoran, House Telvanni, House Sadras, House Indoril, and House Dres. House Hlaalu previously sat on the Council, but lost its seat to House Sadras in the early Fourth Era. Each House governed an eponymous district on mainland Morrowind; Redoran in the northwest, Hlaalu in the western-center, Telvanni in the east, Indoril in the central heartlands and Dres in the southeast. Three of the Houses also had interests in the island of Vvardenfell, and identified themselves by their traditional colors: red for Redoran, yellow for Hlaalu, and brown for Telvanni.
The Gray-Manes are an old and influential clan in Whiterun. House Gray-Mane is a large mansion in the city's Wind District. The clan was one of the first to live in Whiterun, making in likely that the family can trace its roots back to members of the Five Hundred Companions of Ysgramor. Before the Stormcloak Rebellion, the Gray-Manes were friends with their equally venerable neighbors, Clan Battle-Born. However, Clan Gray-Mane strongly supported the Stormcloaks, as well as Ulfric Stormcloak. Clan Battle-Born sided with the Empire. Each clan rallied the city's populace to their respective sides, though Whiterun officially remained neutral.
The Greybeards, an ancient and honored order of monks, live in silence at the ancient monastery High Hrothgar near the summit of the Throat of the World. They are the most famous of the Tongues, or masters of the Voice. Jurgen Windcaller founded the order in response to the Nord army's defeat at the Battle of Red Mountain circa 1E 416. After the battle, he meditated for approximately seven years, and arrived at the conclusion that the power of the Voice should be used primarily as a means of attaining enlightenment, rather than a tool of war. Jurgen called his new philosophy the Way of the Voice, and preached a lifestyle of meditative study of the Voice which the Greybeards carry on to this day.
Contrary to popular misconceptions, the Greybeards are not, strictly speaking, pacifists; the Way of the Voice teaches only that violence is the least of the Voice's uses, and it should be used for that purpose only in times of "True Need". The coming of a Dragonborn is considered such a time, and so the violent use of the Voice by a Dragonborn can be "overlooked", though the other followers of the Way are expected to remain peaceful. While the Greybeards apparently accept almost all who show a talent for the Voice, few can handle the demands of their lifestyle; renowned figures such as Ulfric Stormcloak have either failed to develop their skills or failed to live by the Way. Paarthurnax, the Grand Master of the order, made his home alone above High Hrothgar, at the summit of the Throat of the World.

House Guimard is an aristocratic family of High Rock that claims to have resided in Evermore since the port was founded in 1E 983, three years after the fall of Orsinium. Though earlier accounts of the family are purportedly locked away in their castle vaults, they were publicly documented when High Rock entered into the Alessian Empire in 1E 1029. A citation in the Decretal of Fiefdoms made by Empress Hestra mentions "Barron Guy Marde of ye Rivver Banke".
