- "Few families in Tamriel can boast so many famous figures, wielding so much power over the fate of so many. Our warriors and kings are stuff of legend, and it is not to dismiss their honor and their achievements to say you have heard quite enough about them." — Vorian Direnni, De Rerum Dirennis
The Direnni were an aristocratic clan of Altmer merchants who became a powerful dynasty ruling over High Rock for hundreds of years. They formed the Direnni Hegemony, a loose area of influence around the Isle of Balfiera.
Clan Direnni originated from the small farming village of Tyrigel which sat on the banks of the river Caomus (then called the river Diren hence the family's name) on Summerset Isle. Using his knowledge of alchemy, Asliel Direnni poisoned a barbarian tribe called the Locvar that were continuously raiding Tyrigel. With this external threat dealt with, the way was paved for the future prosperity of the Direnni farms, and generations later they would leave Summerset and travel to mainland Tamriel which would further increase their power and influence.
Clan Direnni rose in power on the mainland through political maneuvering and devious machinations in 1E 355. In 1E 358, the joint army of Cyrodiilic Emperor Ami-El and Skyrim attacked the Clan Direnni in the Western Reach of High Rock.[UOL 1] With the rise of the Alessian Order in Cyrodiil in 1E 361, many Ayleids fleeing Cyrodiil migrated to High Rock to escape the order, and this exodus may have strengthened Clan Direnni as these immigrants were absorbed into their hegemony. Clan Direnni managed to conquer High Rock, some parts of Skyrim and Hammerfell in 1E 477. The Kings of the Colovian West joined with Kvatch and Skingrad to resist the Alessian Hegemony. Soon after, Skyrim under High King Hoag Merkiller and Ryain Direnni of High Rock joined the resistance. Ryain Direnni outlawed the Alessian Reform and put its major advocates to death. Direnni forces began to harass the Colovian West, pushing for the Heartland.
Daggerfall became a minor base of operations for the Dirennis and their allies in 1E 480-1E 482, and the enchantress Raven Direnni was one of the earliest occupants of Castle Daggerfall. It was at that time that Prince Aiden Direnni led the Dirennis against the Alessians in the decisive Battle of Glenumbria Moors, with Raven Direnni, King Laloriaran Dynar of Nenalata, and Hoag Merkiller helping to secure the final victory.
Although the Direnni Clan won the Battle of Glenumbria Moors, they could not regain the power they once had. One by one, control fell to the emerging nobility of Greater Bretony, who seized power throughout most of High Rock within two decades of the Alessian defeat. In the end, only the Isle of Balfiera was left in their hold. Around 1E 500, almost all of High Rock was freed from the Dirennis. Clan Direnni are the only known Altmer ruling family that still remains in human lands.
While most Direnni relocated to the Isle of Balfiera in High Rock, some members of the clan stayed on Summerset, retaining the clan's holdings around the Diren Valley. Some time in the First Era, one of the remaining Direnni—by the name of Lauriel—became highly skilled in the arts of necromancy, to the horror of her family. Facing the possibility of execution, Lauriel refused to repent and claimed that she could not be killed and would only rise again. To prevent Lauriel from doing this, the Direnni buried her alive in a sarcophagus deep below the Direnni Acropolis, and bound her spirit to it by kindling two sacred flames in braziers. A Keeper was then appointed to make sure the braziers remained lit, and the title was passed down between generations. However, the Direnni population on Summerset diminished with time, and they lost contact with their kin on Balfiera. By the mid-Second Era, the last Keeper was long dead, and the braziers had gone out. In time, Lauriel managed to manifest as a ghost, and haunted the Acropolis, hoping to contact and convince someone to release her from her imprisonment. Around 2E 583, the Soulless One entered the crypts of the Direnni Acropolis. Lauriel tried to convince them to release her by burning her remains, while the lingering spirits of the dead Keepers wished to see the braziers relit. It is unknown what decision was made by the Soulless One.
During the Three Banners War, both the Daggerfall Covenant and Aldmeri Dominion used the history of the Direnni against each other in propaganda leaflets. With the Daggerfall Covenant pointing out that they let Clan Direnni live in their borders as proof that they could live with elves in peace . Whereas the Aldmeri Dominion used the history of Clan Direnni to generate sympathy for the Altmer describing their Direnni cousins as "cruelly suppressed".
The master summoners of the Direnni were the first to discover that a conjurer could impose any desired shape on a Flame Atronach, such as that of a horse, which they used in the Battle of Glenumbria Moors.. Peregrine Direnni was also the first to conjure the first ever Flame Atronach in the form of a camel.
- Asliel Direnni is believed to have been the first individual to formulate alchemy into an art and science. As such, some Direnni banners feature an alembic in recognition of his accomplishment.
- Jovron Direnni, an Imperial Battlemage to the court of the Dunmer Empress of Tamriel, Katariah, assisting her in creating peace in a time of turmoil. He was also the grandfather to Medora Direnni.
- Pelladil Direnni, who shared a similar role with the first ruling Potentate, Versidue-Shaie, and encouraged the Guild Act which allowed for the creation of the Mage's Guild and Fighter's Guild. Pelladil was also responsible for the construction of Blackrose Prison. He was the great great grandfather to Jovron Direnni.
- Raven Direnni, with her better known cousins Aiden and Ryain, brought an end to the tyranny of the latter Alessian Empire. Before the Psijics of Artaeum, it is said, she created the art of enchantment, learning how to bind a soul into a gem and use that to enchant all manners of weaponry. One known creation of hers is an inflammable rug, which was supposedly one of her first creations after she discovered the principles of enchantment.
- Chimere Graegyn was a human retainer of the Direnni, and a master of conjuration. He was cast into Oblivion and forbidden to die after scheming against Mehrunes Dagon circa 3E 172, trapped in the Chimera of Desolation for all eternity.
- Corvus Direnni was the Arch-Conjurer of clan Direnni at some unknown point and mentored students for the Master Conjurer test. 
- Prince Aiden Direnni, who led Direnni forces to victory against the Alessians in the Battle of Glenumbra Moors in 1E 482
