Glenmoril Wyrd
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, and in time many became hagravens.
 Grand Council
- The Great Houses hate each other -- theft, murder, assassinations, secret raids, standard stuff. -- Hasphat Antabolis
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 north-west, Hlaalu in the western-center, Telvanni in the east, Indoril in the central heartlands and Dres in the south-east. 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 Great House traditions derive from ancient Dunmer clans and tribes, but now function as political parties. Differences are now rarely settled by armed conflict, but instead through squabbles in the Grand Council and, for a time, through the execution of formal Writs by the once-honorable assassins of the Morag Tong. Dunmer Great House membership is largely a matter of birth and marriage, but Imperial colonists may also become retainers of a Great House, or may be adopted into a Great House. Initially an outlander may gain status in a house as an oath-bonded hireling, pledging exclusive loyalty to a single house and forsaking ambitions with all other houses. Later, after faithful service and advancement in lower ranks, an outlander may seek adoption into a Great House. Adoption and advancement to higher ranks in a Great House requires that a Great House councilor stand as sponsor for the candidate's character and loyalty. Finding a councilor to sponsor an outlander often involves performing a great service for the prospective sponsor and the Great House in question.
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, who founded the order in the fifth century of the First Era, believed the power of the Voice was a means of attaining enlightenment. 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, thus the violent use of the Voice by a Dragonborn is "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 Balgruuf the Greater and 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.
