Elder Scrolls Online lore: The game is set in 2E 582 during the Interregnum, a period of time between the assassination of Savirien-Chorak and the rise of Tiber Septim, where there was chaos, bloodshed, and no Emperor on the Ruby Throne.
Several years prior, the Cyrodilic Emperor Varen Aquilarios desired to become Dragonborn in order to light the Dragonfires in the Imperial City, thus legitimizing his claim to the Ruby Throne. The sorcerer Mannimarco was able to convince him that he knew a ritual that could accomplish this, but that it required the Amulet of Kings. Along with the leader of the Dragonguard Sai Sahan, the half-giant Lyris Titanborn and the High Chancellor of the Elder Council, Abnur Tharn, they became the Five Companions. They were able to retrieve the Amulet of Kings and begin the ritual in 2E 578. At that moment, Mannimarco used his dark magic to immobilize the others and reveal his true intentions: he was an agent of Molag Bal, and the ritual in fact weakened the barriers between Nirn and Oblivion in an event known at the Soulburst. This event allowed Molag Bal to initiate the Planemeld, a forceful merging of worlds. Once the ritual was completed, aftershocks were swept across every corner of Nirn. Mages died or went mad, Red Mountain trembled in Morrowind, earthquakes shook Skyrim, and heavy storms devastated the coastlines of Elsweyr and Valenwood. The constellation of the Serpent grew so large that it seemed to threaten every star sign at once.
The Tharn family, rulers of Cyrodiil through Empress Regent Clivia Tharn, made a pact with Mannimarco, the King of Worms, who has agreed to supplement the Imperial’s forces by resurrecting their soldiers, except for Clivia’s father Abnur, who opposes Mannimarco. Secretly, Mannimarco is a servant of Molag Bal, the Daedric Prince of corruption and domination. Molag Bal is harvesting the souls of mortals for more power. The hero, known as the Vestige, is an adventurer whose soul has been taken, which allows them to constantly return to life. The player is killed by Mannimarco in a sacrificial ritual and they are brought to Coldharbour, where they awaken to find a mysterious man known as the Prophet, who, with the help of Lyris Titanborn, helps the Vestige escape Coldharbour, freeing the Prophet, but also imprisoning Lyris within Coldharbour. Once the Vestige escapes Coldharbour, they awaken in Tamriel and are let loose upon the dangerous world.
