The first Mages Guild is formed by Vanus Galerion the Mystic and Rilis XII in Firsthold, Summurset Isle, mostly as an answer to the reluctancy of the Psijics Order to deal with its evil member, Mannimarco, the leader of the Necromancers.

"Like a tree from an acorn, the Mages Guild grew branches all over Summurset Isle and then to the mainland of Tamriel. There are many records of superstitious or sensibly fearful rulers forbidding the Guild in their kingdom, but their heirs or their heirs' heirs recognized the wisdom of allowing the Guild to practice. The Mages Guild was a powerful force in Tamriel, a dangerous foe if a somewhat disinterested ally. There have been only a few rare incidents of the Mages Guild actually becoming involved in local political struggles. On these occasions, the Guild's participation has been the ultimate decider in the conflict."

Circa 2E 360

The Dark Brotherhood is secretly established by members of Morag Tong who want the guild to be more secular and general. The new assassin guild accepts contracts from everybody, instead of just the certain class of Dunmer society.

"The important distinction between the Dark Brotherhood and the Morag Tong was that the Brotherhood was a business as much as a cult. Rulers and wealthy merchants now used the order as an assassin's guild. The Brotherhood gained the obvious benefits of a profitable enterprise, as well as the secondary benefit that no longer could rulers actively persecute them. They were needed. Even an extremely virtuous leader would be unwise to maltreat the Brotherhood."

After Hammerfell and Morrowind, Tiber Septim turns his attention fully to the Aldmeri Dominion. The joined Elven kingdoms proves too powerful, and Septim's Armada repeatedly defeated. Tiber Septim uses his latest weapon, the Numidium (Anumidum). A Dwemeri giant construct as a result of the deal between Tiber Septim and Vivec. Numidium crushes the Aldmeri armada and armies and in short time the Aldmeri Dominion surrenders.

"Nothing is known of the circumstances of the personal meeting between Septim and Vivec, or where it took place, or the preliminaries which must have preceded the treaty. The public reason was to protect the identities of the agents involved. In the West, speculation has centered around the role of Zurin Arctus in brokering the agreement; in the East, rumors suggest that Vivec offered Numidium to aid in the conquest of the Altmer and Summerset Isle in return for significant concessions to preserve self-rule, house traditions, and religious practices in Morrowind."
- from Erramanwe's On Morrowind: the Imperial Province

Numidium was not in the state of operational when it was presented by Vivec. Zurin Arctus brings the pieces of Numidium to Halls of Colossus in Elsweyr to be assembled. There is unwritten statement that a Dragon Break occurred during the reconstruction of Numidium. The official records state that Zurin Arctus sacrifices his soul (heart) to be infused into a gem called Mantella to be implanted into the Numidium in order to make it operational. Another version of the event is recorded in"Arcturian Heresy." It is written that the King Wulfharth, the Underking of this version, was tricked by Zurin Arctus and Tiber Septim. Zurin Arctus managed to trap the soul of the Underking into Mantella. However, Arctus was killed in the process.

The official records state that after the demise of the Aldmeri Dominion, disagreement between Zurin Arctus and Tiber Septim arises. Arctus tries to reclaim his soul in Mantella and opposed by Septim’s forces. The final battle destroyed Numidium to pieces and the Mantella is hurled to Aetherius. Arctus retreats and without his life force, he goes into a semi-slumber in a subterranean vault. He is known as the Underking.

In the centuries that follow, Septim's elite soldiers (the Blades), for generation after generation, collects the pieces of the Numidium. The Underking continously sends his agents to find a way to recover Mantella throughout Tamriel and becomes the enemy of the Septim Dynasty.
