Mace of Aevar Stone-Singer
The Mace of Aevar Stone-Singer (also called the Mace of Aevar Stonesinger) is a prized Skaal artifact. According to legend, the eponymous hero used the mace to amplify the Song of the Earth, returning the Gift of the Earth and making the land rich again for the Skaal.
It is traditionally awarded to anyone who completes the Ritual of the Gifts, a sort of pilgrimage around Solstheim practiced by the Skaal. Though a magnificent and lethal stalhrim weapon which inflicts frost damage on foes, the mace is also extraordinarily heavy.
Mace of Molag Bal
The Mace of Molag Bal, also known as the Vampire's Mace, is a Daedric artifact attributed to Molag Bal, the Lord of Domination and Enslavement. Its enchantment drains the stamina and magicka of its victims and transfers them to the bearer. It also has been known to have the ability to transfer an enemy's strength to its wielder or trap their soul. It has been said to be a good weapon of choice for vanquishing wizards.
Many legends surround the mace, but its origins can be traced back to when Molag Bal deceived an Orcish blacksmith and enslaved him in pits of Coldharbour. The blacksmith was turned into a Soul Shriven and forced to forge the mace.
Due to Molag Bal's penchant for meddling in mortal affairs, he grants the mace to those he deems worthy but has also been quite free with his artifact. Molag Bal assumes that when such a powerful artifact falls into mortal hands, a trail of death and destruction is sure to follow. Some believe the mace to be an object of Daedra worship.
Mace of Slurring
The Mace of Slurring was crafted near the end of the Second Era by Kyanka, a slightly deranged Altmer weaponsmith and enchanter. He had a rather warped sense of humor, and apparently delighted at the thought of reducing opponents to a gibbering mess before crushing them to death. However, the mace saw little use.
The Mantella was a massive green gem, a "Crux of Transcendence" that contained the "heart", or life force, of the entity known to Tamriel as the Underking. Twice, the Mantella was used to power the gigantic brass golem, Numidium—first by Tiber Septim when he conquered Tamriel, and again during the events of the Warp in the West.
The Mantella was lost after Tiber Septim's conquests. For most of the Third Era, the Mantella was hidden on a plane of Aetherius known as the Mantellan Crux. It was later located by Nulfaga the sorceress and recovered by an agent of the Blades, which led directly to the Miracle of Peace.
The Mask of Alkosh
The Mask of Alkosh is a holy relic of the Dragon-Cat Alkosh, worn by the champions of the Pride of Alkosh. It was first worn by the Ja'darri the Endless, the first champion of Alkosh and the founder of the Pride of Alkosh. A Dragon must awaken the dormant power within the mask before it can be used. When the mask is empowered, it imbues its wielder, known as a Mask-Bearer, with extraordinary power.
Masque of Clavicus Vile
The Masque of Clavicus Vile (also known as The Masque of Clavicus) is a helm which makes the wearer more popular wherever he or she might go. Much like other Daedra and their artifacts, Clavicus seems to retain ultimate control of the Masque and may recall it without warning.
The best known story of the Masque tells the tale of Avalea, a noblewoman of some renown. As a young girl, she was grossly disfigured by a spiteful servant. Avalea made a dark deal with Clavicus Vile and received the Masque in return. Though the Masque did not change her looks, suddenly she had the respect and admiration of everyone. A year and a day after her marriage to a well connected baron, Clavicus Vile reclaimed the Masque. Although pregnant with his child, Avalea was banished from the Baron's household. Twenty one years and one day later, Avalea's daughter claimed her vengeance by slaying the Baron.
The Mechanical Heart, also referred to as the new Heart of Lorkhan, is a mechanical replication of the Heart of Lorkhan created by Sotha Sil. It first began development shortly after the events that occurred in 2E 882, where Dagoth Ur awakened and then ambushed and nearly killed the Tribunal during their annual pilgrimage to Red Mountain to renew their divine powers. The event resulted in the Tribunal being cut off from access to the Heart of Lorkhan, and the Mechanical Heart would as a response begin development as a backup to the loss of the original Heart of Lorkhan.
Mehrunes' Razor (sometimes Mehrunes Razor), also called the Dagger of the Final Wounds, the Bane of the Righteous, and the Kingslayer, is a Daedric artifact created by the Daedric Prince Mehrunes Dagon. This powerful ebony dagger has the ability to kill instantly, as there is a small chance that Dagon will claim the souls of those struck by the Razor. It is Daedric in appearance, emblazoned with Daedric script and seemingly able to drink the light that hits it.
The Dunmer Talym Rend became a pawn in Sheogorath's game when he struck a deal with Sheogorath to forget the painful memories of his involvement in the Worm Cult's ritual sacrifice of his son Novos. Sheogorath manipulated his mind for "motivation," and tricked him into thinking his son was alive, and that he was fighting to cure his son of his madness instead.
The prince requested three souls driven mad in return for restoring Talym's son Novos to sanity. Once Talym had driven his three targets to Sheogorath's embrace, Talym returned home only to realize that Novos had been dead the entire time. When Talym set out to gain an explanation from Sheogorath, he was only turned away. Unanswered questions ate away at his sanity as he wandered endlessly around the Shivering Isles.
Eventually, he regained a semblance of composure and journeyed to Knifepoint Hollow. There, Talym was informed by Dyus, the librarian of Jyggalag, that he might gain an audience with Sheogorath if he retrieved an artifact of Jyggalag. He retrieved the Sword of Jyggalag and confronted Sheogorath. Using the memory wand, Sheogorath revealed Talym's original intent along with his memories. He proceeded to mock Talym, angering him and inciting a duel. The Daedric Prince of madness was defeated when Talym turned the memory wand against him, forcing the Prince to recall his memories of his previous life as the Daedric Prince of Order, Jyggalag, and pleaded for him to stop the madness. He fulfilled Talym's wishes and would leave him and his companions free from his grasp.
The High Wizard Carni Asron is said to be its creator, and he loaned it to apprentices while they were studying under him. After Asron's death, the ring and several other of his possessions vanished and have been circulated throughout Tamriel.
The Mnemic Egg is an Argonian relic that can act as the physical link between the Argonians and the Hist. It is a sacred symbol of birth and life, containing the memories and wisdom of the Hist. The Mnemic Egg takes the form of a mortal-sized seed infused with Hist sap, which visibly flows and pulsates throughout the Egg.
When a Hist tree dies, the death is described as the tree being "born backwards." That is to say, the death of a Hist creates a Mnemic Egg. The memories of that Hist and its Argonians are all contained within the Mnemic Egg. The Hist share a collective consciousness; they have the ability to communicate with one another, and to feel what another Hist is feeling. As a result of the Hist's shared connection, and the fact that the Mnemic Egg is a physical vessel for all of the memories of the dead Hist that birthed it, the Mnemic Egg can be used as a gateway into the collective consciousness of all Hist Trees. This also means that in the wrong hands, a Mnemic Egg can be used to sever the Argonian connection to the Hist.
Moon-and-Star is a Dwarven ring of Chimer hero Nerevar. The artifact was forged by one of the smiths of Dwemer Sorcerer-priest Kagrenac and blessed by the Daedric Goddess Azura. The ring lent Nerevar supernatural powers of persuasion and indisputable proof of identity, since any other who tried to wear it would be killed instantly. The Moon-and-Star helped Nerevar unite the warring Chimer clans, and form the First Council which included the Dwemer.
Moon-and-Star played a role in the Nerevarine Prophecies, as it allowed the Nerevarine, the reincarnation of Nerevar, to again unite the Great Houses and Ashlander clans, this time in the battle against the forces of Dagoth Ur.
The Moonlight Blade is a crescent moon-shaped blade associated with both Azurah and the extant Order of the Hidden Moon. This ancient Khajiiti order was said to have been gifted the blade by the Mother Goddess herself and were charged to guide, protect and redeem their people's souls—both pure and those corrupted by Namiira, the Moonlight Blade was considered sacred tool for this duty. While on its own the blade was a deadly weapon against the Dro-m'Athra, in the hands of those who knew the Order's secrets, the Moonlight Blade could cut through liminal barriers, both the mundane and those between worlds.
The Mortuum Vivicus was a powerful weapon created by the Daedric Prince Molag Bal. It had no physical form, instead appearing as a large orb of cold light. It was originally given as a gift to the Ayleid King Anumaril of Abagarlas, a Daedraphile settlement on City Isle that was dedicated to Bal.
Muatra, meaning Milk Taker, is a spear wielded by Vivec, one of the living gods of the Tribunal. While there are no accounts of its creation, Vivec claimed it was used by him to eliminate his progeny with Molag Bal "from a secret he had bitten off from the King of Rape".
The Mysterium Xarxes was a tome written by Mehrunes Dagon, who scribed it in "the deserts of rust and wounds". It was an artifact of great—and evil—power. The Xarxes was said to have a vile corrupting influence; reading from the book required magical protection from its powers, even merely handling it was said to be dangerous.
The book was given by Dagon to Mankar Camoran. After studying the tome, Mankar wrote the Commentaries on the Mysterium Xarxes (also known as the Mythic Dawn Commentaries). Inspired by the prophecies and promises within the book, Mankar founded the Mythic Dawn, a Daedric cult devoted to Mehrunes Dagon. The Xarxes acted as the cult's holy book, and was stored in the Mythic Dawn's hidden shrine in the caverns beneath Lake Arrius in Cyrodiil. Using the power of the book, Mankar created Gaiar Alata, or "Paradise", an alternate realm where the souls of Mythic Dawn cultists went in death.
In 3E 433, following the Mythic Dawn's assassination of Emperor Uriel Septim VII and all of his legitimate heirs, the Blades infiltrated the cult and stole the Mysterium Xarxes from their shrine to Mehrunes Dagon. It was taken to Cloud Ruler Temple, where Martin Septim, the illegitimate son of Uriel and the heir to the throne, translated the Xarxes and discovered a way to create a portal to Camoran's Paradise. The ritual required a Great Welkynd Stone, a Great Sigil Stone, a Daedric artifact, and an Aedric artifact. The Hero of Kvatch entered Gaiar Alata and defeated Camoran, retrieving the Amulet of Kings. The Mysterium Xarxes was destroyed in the process.
