I will talk about the whole story of High Isle and Galen so don't read if you don't want to get spoiled.
When Zenimax promised that the 2022 story arc would circle around political intrigues instead of the estival world saving I was cautiously optimistic. I mean, we already had a bad start with the introduction of yet again another cult of freaks (I swear there are more cultists than civilians in Tamriel at this point) but I guess that for game design purposes we needed a new flavour of mercenaries to bonk on the head.
High Isle main quest was... good. The disappearance of the alliance leaders was a serious yet realistic issue, we could finally meet Arabelle Davaux, the villains seemed well organised, High King Emeric carried most dialogues as usual, all good stuff.
It was obvious right away that the Ascendant Lord was Bacaro, mostly due to the small cast of male characters and his good guy act, but also because he had the best motives than any other villain in ESO (or so I hoped).
Picture this. Lord Bacaro is an Imperial whose country has been torn apart by a daedric invasion. Molag Bal's minions wreck havoc in the Imperial City while the souls of countless mortals are stolen. You would expect said mortals to set aside their differences and band together to deal with this catastrophic event. After all they had already done so during previous invasions when the stakes were much lower. Alas in a collective streak of short-sighted greed, the three Rulers decided that this would be the best time to capture the Ruby Throne for themselves. So now on top of fighting daedras mortals also have to fight against each other, causing even more deaths and throwing Cyrodiil into an unending crisis. The Leaders could have used the Vestige's attack on Molag Bal as a distraction to get Cyrodiil under mortal control again before splitting their gains, however they couldn't even form a truce at this crucial moment. It looks like politicians bickering about the colour of the oval office carpet while Satan does donuts on the White House lawn.
Meanwhile, Lord Bacaro founded the Society of the Steadfast to heal any soldier injured in the war and help refugees. The thing is that he doesn't have infinite ressources, his country is in ruins with no peace in sight, and no one cares. I too would be pissed.
Clearly, people's lives mean nothing to the Leaders. All of them whine that Tamriel would fall into chaos under their opponent's rule but chaos is not only there already but also getting worse because of them, proving that none of them are fit to sit on the Ruby Throne.
Bacaro's plan is perfect. Under the pretense of a peace summit that he assumes they'll want to attend just for good PR, he invites the Leaders on his turf to get them killed in an accident, ridding Tamriel of its tyrants. Then thanks to his good reputation as the benevolent Society of the Steadfast leader, he would be able to assemble some forces to go save Cyrodiil.
Since as a player we have no choice in the story, we would still have to save the Royals and stop Bacaro. We wouldn't have to sneeze on
kill him halfway during his bad guy monologue however, we would arrest him and get him trialed for attempted regicide. As it would be a pretty bad political move to make Bacaro a martyr, he would simply be imprisoned while the Leaders work on a peace treaty to appease the discontent people.
So in a way Bacaro still succeeds in ending the war.
Really, the Ascendant Lord's offical motivations already made him a great villain, a antihero even, there was no need to muddy it with a hidden agenda.
Because yes, this whole text is a fanfiction, his real motivation is that he's actually related to a druid king and he will use his newfound magical powers to make a volcano explode and RULZ oVeR tHe wOrLDDD. What does this have to do with the alliance leaders ? Or the Society of the Steadfast ? Why shoehorning the druids in the main quest when the Three banners War doesn't even concern them ? Why ruining Bacaro's journey by turning him into a tired and overused cartoonish baddy ?
Also ZoS, you lied. This was another end of the world scenario.
