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.
During the Alessian Slave Rebellion, the Ancestors were dispersed to cities across Cyrodiil for safekeeping (specifically Culotte, Fanacas, Mackamentain, Moranda, Ninendava, Vilverin, Welke, Wendelbek, Wendir and Wenyandawik). Following the sacking of White-Gold and the Ayleid exodus of Cyrodiil, the statues were left behind and forgotten.
In 3E 433, an Altmer nobleman called Umbacano paid the Champion of Cyrodiil to hunt down the Ten Ancestors so that he could add them to his collection of Ayleid antiquities. He then put them on display in his private manor in the Imperial City, before his untimely death that same year while exploring the ruins of Nenalata.
Totem of Claw and Fang
The Totem of Claw and Fang is a powerful artifact sacred to the Skaal of Solstheim. It is a totem used in religious rituals to invoke powerful nature magic. Its primary function is the summoning of a Spirit Bear, which is then tracked down and killed by the Skaal to please the All-Maker during the Ristaag, a ritualistic hunt. The bear aspect of Hircine, Hrokkibeg, is represented through it.
The Totem was stolen from the Skaal at one point. Believing that it would not again be needed, the Skaal did nothing to recover it, and it eventually came to rest in the Tombs of Skaalara on Solstheim's northeastern coastline.
In 3E 427, the Skaal once again required the Totem in an effort to counteract the Bloodmoon Prophecy, and attempted to retrieve it from the tomb. Hircine wished to prevent its recovery, and sent his Hounds to guard the tomb. The werewolves were ultimately unsuccessful in guarding the Totem, and the Skaal initiated the Ristaag.
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 craftmanship. 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.
