The following article CONTAINS SPOILERS. So you have been warned!
In the end, Tharn vanishes and takes the Amulet of Kings with him. At least that is what Cadwell tells us when we are returned to the Harborage by Meridia. Maybe Tharn will play a role in the next crisis.
Some moments later Varen Aquilarios appears to us and he brings us a warning: "Oblivion stirs. Great and terrible machinations have begun. [...] Once again, Tamriel is in danger." Suggesting that a great event will happen in the future. He continues: "A [great] war between the forces of Oblivion [is coming]. The Deadric Princes are choosing sides. The great deceiver, the sewer of discord and the patron of darkness plot a great deception." Varen refers to a great war that will happen in the future in which three Deadric Princes will work together to plot a great deception.
The Deadric Princes
The first Prince is the great deceiver. Possibly Varen is possibly refering to Boethiah (or Boetia), who is the Deadric Prince of deceit, conspiracy, treachery and sedition. Boethiah is mostly depicted as a female Prince, however it is not clear. Dunmer worship her as one of the three "good" Deadra along with Azura and Mephala. It is known that Boethiah and Molag Bal developed a rivalry between each other.
The second Prince Varen possibly refers to is the sewer of discord. In lore Mephala is depicted as the Prince of unknown plots and obfuscation, a master manipulator and a sewer of discord. The best known worshippers of Mephala are the Morag Tong. Who are a long time rival of the Dark Brotherhood. Mephala is also a "good" Deadric Prince, but Mephala is known for lying and her secrecy. According to lore, Mephala played a large role in the Reclamations after the eruption of the Red Mountain in the Fourth Era. In which the three "good" Deadric Princes were reclaiming heir status from the Tribunal.
Last Varen mentions the patron of darkness. Nocturnal is mostly refered to as the Deadric Prince of darkness, night and luck. Also known as the Mother of Night. Nocturnal is also known for deception but is seen as not as violent as Boethiah. This Deadric Prince is by some considered a sister of Azura. She is not worshipped like other Deadric Princes by priests. There are some mortals who claim to be priests of Nocturnal but her true followers (and puppets) are the Nightingales. Besides that people that operate in the dark like to worship Nocturnal, mostly thieves and spies.
The great deception
Further more, Varen mentions they are plotting a great deception. Looking at the timeline after The Three Banners War started in 2E 582, there are a few interesting historical moments. But the most significant moment is the awakening and emerging of Dagoth Ur in Morrowind (2E 882).
In the first Era, the Heart of Lorkhan was found by Indoril Nerevar and Dagoth Ur (then known as Voryn Dagoth) inside a Dwemer stronghold. There are three different stories of what happened that day.
One story states that after consulting their advisors they did nothing with the Heart. They made a vow to Azura and left the tools of Kagrenac alone. However when Indoril returned to Dagoth, he had turned mad by the power the Heart offered. Nerevar killed Dagoth in a fight, but was mortally wounded and died. Just before he died he made his advisors, who found him bleeding, vow to never use the tools themselves. However they eventually did and turned themselves into gods. Azura then cursed the Chimer race and made them into the Dunmer with their characteristic skin and eye colour.
Ashlander texts, however, tell a different story. Nerevar was not killed by Dagoth Ur but by his advisors. Known as Vivec, Almalexia and Sotha Sil and trusted members of the Tribunal. They tried to kill Nerevar to gain more power and use the tools of the Heart to become immortal.
In another story Nerevar died as a result of the Battle of Red Mountain.
In all accounts however there is a plot that takes place. A plot against Nerevar and mostly against the advice of Azura. This plot of a great deception Varen refers to is most likely a similar plot. In the plot "the Daedric Princes are choosing a side" It could be that Boethiah, Mephala and Nocturnal will plot again against Azura.
The lost city of Sotha Sil
This is very likely, because in the main quest Varen continues with the line: "The war shall begin when the gates of Sotha Sil's lost city are re-opened". Varen is refering to the three immortal god-kings of Morrowind to plot against Azura. They play a large role in the story of Nerevar.
The lost city of Sotha Sil, Varen is refering to, is the Clockwork City. Sotha Sil was the greatest wizard and the wisest counciler of the First council. The death of Nerevar allowed the three god-kings to tap into the power of the Heart of of Lorkhan to become gods themselves. Before that they were mortal. Sotha Sil did this together with Vivec and Almalexia. Vivec is known to be a "transcendent evolution" of the Deadric Prince Mephala. Almalexia is known as "the anticipation of Boethiah". Maybe Sotha Sil is getting help from Nocturnal? The lore is not clear about this subject, but it is very likely to be true. What we do know from the lore is, that Nocturnal is the sister of Azura. So this continuation of the story could be a family matter.
Dahoth Ur returns
But most of the story told so far happens in the First era. And Elder Scrolls Online takes place in the Second era. In other words, this entire plot may be a very different one. For that we have to dig deeper into the lore and find out what happened when Dahoth Ur returns. In 2E 882 the three immortal god-kings of Morrowind wanted to renew their immortality and their powers. But Dahoth Ur had been drawing power from the Heart of Lorkhan and had become so powerful that they could not enter the red mountain. Drawing more power from the Heart, the Tribunal grew weaker. He used his power to start the creation and keep the secrecy of the Akulakhan (also known as the Second Numidium). A giant reconstruction of the machine god used by Tiber Septim. With his goal to take control of Tamriel.
The Nerevarine prophecy
After the treason of the three immortal god-kings against Azura, Azura swore that she would resurrect Nerevar to make things right again. According to the prophecy, "A prisoner born on a certain day to uncertain parents" would be send. Maybe in the new story, we will be that Nerevarine.
What do you think?
Let us know in the comments below what you think about this theory. Could this be true, or do you think another event will be the start of a new story in The Elder Scrolls Online.
There are some more interesting events in the lore that could be part of the continuation of the story of ESO:
In circa 2E 730 The isle of Artaeum returns following 500 years of absence.
- This could be a possibilty for a new zone
In 2E 827 Talos, later known as Tiber Septim, the first Emperor of the Septim dynasty, is born.
- Talos could play a role in the story
In 2E 830 the Altmeri Dominion is reformed and the Thalmor are established as a provisional government.
- This could open a complete new line of quests in Aldmeri Dominion zones.
In 2E 852 General Talos destroys the allied Nord and Breton in the citadel of Sancre Tor. Resulting in the Nord captives to join General Talos' army and the crowning of General Talos as Emperor Tiber Septim.
- This event could mean that the Three Banners War changes significantly. Maybe a fourth Alliance will be introduced into the war including the Nords, Breton and an unknown faction.
In 2E 682 Tiber Septim claims most of the independent empires and consolidates them into the Empire.
- This could open completely new quests and an entire different experience of Tamriel as we know it today.
