The Tamrilean Tractates is an ancient and historic record written by an author named Khosey in 1E 200. It dates back to the early First Era and it provides early accounts of human history in Tamriel and information regarding Cyrodiil's geography and environment.
It was notably written in Old Tamrielic. It is often referenced by scholars after many years of its creation, but the extent and the full content of the book are currently unknown. However, based on the scattered information regarding the Tamrilean Tractates, it mostly covers the information contemporary with the book, such as the Alessian Slave Rebellion, and the northern conquests of the First Empire of the Nords. The book is famously credited for providing a firsthand account of the early Bretons, as well as miscellaneous information, such as early accounts of the Troll and the jungles of Cyrodiil.
The Ten Ancestors are a set of ten Ayleid statues. They consist mostly of meteoric iron prongs, with a shard of meteoric glass in the center. The statues played an important role in Ayleid religion and were displayed in the Temple of the Ancestors, now known as the White-Gold Tower. The temple of Loriasel was also built in Black Marsh by the Barsaebic Ayleids in veneration of the Ancestors.
The Ancestors themselves were believed to worship the Daedra, and Daedraphile Ayleids accordingly followed the Eleven Edicts of the Ten Ancestors. The Heretic of Lindai was known for writing the Eleven OTHER Edicts of the Ten Ancestors, a parody that supposed the Ancestors worshipped Auri-El instead.
Totem of Claw and Fang
The Totem of Claw and Fang is a religious artifact sacred to the Skaal of Solstheim. It is used in their rituals to invoke powerful nature magic to summon the Spirit Bear, which is then tracked down and killed by the Skaal to please the All-Maker during the Ristaag. Hircine's bear aspect Hrokkibeg is also associated with the Totem, and the Skaal and Hircine have come to conflict over it.
Totems of Hircine
The Totems of Hircine are ancient artifacts of Hircine, predating mens' ability to write, speak, and properly think. The first is the Totem of Fear, an engraved and feathered wolf skull that is said to have been used by shamans in blood ceremonies to create Lycanthropes. It augment's a werewolf's presence, making people cower in fear save for those that have caught a glimpse of Hircine's face. It is said to be worn by Storihbeg the Manbeast, a wolf aspect of Hircine. The second is the Totem of the Hunt, an engraved thigh bone that augments a lycanthrope's sense of smell and sound. The third is the Totem of the Brotherhood, a mundane drum that allows the summoning of pack members.
Totem of Tiber Septim
The Totem of Tiber Septim is an artifact that allows its bearer to control Numidium, the ancient Dwemer construct. It was created at the end of the Second Era by Imperial Battlemage Zurin Arctus, to allow Emperor Tiber Septim to use the golem in his conquest of Tamriel. Only an individual of noble blood or special supernatural affinity can safely wield the Totem; it will reject an unworthy owner, and has been known to telepathically do so to such individuals.
The Totem was lost along with Numidium shortly after the conquest of Tamriel, when the automaton was destroyed by the Underking. It was known to have resurfaced in the Iliac Bay region some time around 3E 401. After changing hands several times over the next few years, it was recovered by a mysterious adventurer sent by Emperor Uriel Septim VII.
In 3E 417, the Totem was simultaneously given to (and used by) seven factions around the Iliac Bay. This caused the phenomenon now known as the Warp in the West, during the events of which the Totem was apparently lost again.
Trueflame, or the Blade of Nerevar, is a one-handed Dwemeri sword from the early First Era. Trueflame and its twin blade, Hopesfire, represented the pinnacle of Dwemer craftsmanship. The twin blades possessed unearthly fire enchantments. They were presented as wedding gifts to Lord Indoril Nerevar and Almalexia by the Dwemer King Dumac. Trueflame was shattered during the Battle of Red Mountain circa 1E 700, and the pieces were lost. It possessed the ability to kill a god if wielded by one of noble intent.
