Bal Molagmer
The Bal Molagmer, meaning "Stone Fire Men" in Dunmeris, were a group of righteous thieves from Vvardenfell who died out early in the Third Era. Although the Bal Molagmer were thieves, they stole only from the unjust and gave to those in need. The Bal Molagmer carried burning stones from the Red Mountain, and their special protective gloves became the symbol of the group.
In 3E 427, Gentleman Jim Stacey, who was the master thief of the Thieves Guild on Vvardenfell, attempted to rekindle the now-legendary Bal Molagmer. This move was likely an attempt to appeal to the local Dunmer, who preferred the Camonna Tong to the Imperial Thieves Guild. Stacey made the new Bal Molagmer a subfaction of the Guild, and enlisted his best thieves to continue the tradition of aiding the poor, using the group's distinct gloves to give the impression that the Bal Molagmer had returned. The ultimate fate of this subfaction is unknown.
 Bards College
The Bards College is a school for music in Solitude. The Bards College is where any aspiring bard, sometimes called a skald in Skyrim, starts his career in tale-telling and song. Many famous bards have trained and taught at the College. It is traditional for new Bards to perform a service to the college, then they are formally inducted at a ceremony performed annually at a festival, the Burning of King Olaf. The College's festival was nearly halted during the Fourth Era because Jarl Elisif the Fair thought it unbecoming. When a prospective bard rediscovered the lost King Olaf's Verse and it was performed for the Jarl, she was persuaded to allow the festival to continue as a righteous celebration of triumph over tyranny.
The Battle-Borns are a rich, influential clan in Whiterun who staunchly supported the Empire in the Stormcloak Rebellion. 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. The Battle-Borns were old friends with their neighbors, the equally venerable Gray-Manes. However, the clans began feuding when the Gray-Manes sided with the Stormcloaks during the Stormcloak Rebellion, while the Battle-Borns remained loyal to the Empire. The clan also attribute the feud to the Gray-Manes' jealousy over their wealth.
The House of Clan Battle-Born stands near the Gray-Mane residence in Whiterun's Wind District. The Battle Borns also own the profitable Battle-Born Farm just outside the city. Olfrid Battle-Born was the clan's vocal patriarch. The Battle-Borns may have been involved in the abduction of Thorald Gray-Mane by the Thalmor. Each clan rallied the city's populace to their respective sides, though Whiterun officially remained neutral.
 The Beautiful
A violent group of militants that appeared during the Third Era in Summerset Isle. These radicals sought to destroy significant monuments and assassinate traditional leaders in an attempt to further modernity and reject their Altmer heritage. They are mentioned in the third edition of the Pocket Guide to the Empire.
 Benevolence of Mara
Followers of Mara typically form temple organizations called Benevolences, which are devoted to the charge of uniting all creatures as brethren, children of the Mother Goddess of Tamriel. They are intolerant only of those who show intolerance and hate. Mara blesses all with the gift of love, but particularly favors those who help her followers in Tamriel. For a reasonable donation to a Benevolence, the patron will be blessed and supposedly be forever beloved by he or she who loves them best. Those who devote themselves further to the Mother Goddess are even more blessed. The Benevolence's priests and priestesses study the greatness of Mara's Tamriel and are said to have learned much, so there is much secret knowledge that is shared with initiates who are judged to be true to Mara's calling.
 Berne Clan
 Blackwater Brigands
The Blackwater Brigands were a group of four pirates based in Bravil, who were active in the late Third Era. They were destroyed during their attempted capture of the Bloated Float, when a passenger onboard the ship single-handedly killed or captured all four brigands.
 Blackwood Company
A mercenary company founded around the end of the Third Era. The company was named after both the Blackwood region and the "thoghatt" or "charcoal warriors" of Khajiit tradition. Based in Leyawiin, they competed with the Fighters Guild for contracts, although they were less regulated. The Blackwood Company had been exploiting a sick Hist tree smuggled from Black Marsh in order to strengthen their warriors in battle. This however had a side effect of causing all those who ingested it, even Argonians, to hallucinate.
The Blades were the hidden Eyes and Ears of the Septim Emperors in the provinces of Tamriel. Originally tasked with collecting far-flung fragments of Numidium, they became a prestigious service order for citizens demonstrating the greatest loyalty to the Emperor. To be named in the Blades by the Emperor is a great honor, and publicly acknowledged members serve openly in noble courts and diplomatic posts. Privately, many Blades members act as the Empire's intelligence agency. Such agents conceal themselves with secret identities, operating in disguise as couriers, observers, spies and bodyguards throughout the Empire.
The Remanada traces the history of the Blades to the original Akaviri bodyguard of Reman Cyrodiil. According to this legendary account, the same immortal Akaviri pledged themselves to Cuhlecain in order to aid General Talos' ascent to the throne. Their ancient stronghold, Cloud Ruler Temple, is located in the Jerall Mountains.

 Blood Horkers
Blood Horkers were a group of pirates which operated along the northern shores of Skyrim during the Fourth Era. The Stormcloak Rebellion preoccupied the powers in the area, allowing the Blood Horkers to prey on merchants sailing through the Sea of Ghosts with little opposition. They were eventually decimated by mercenaries hired by the East Empire Company.
