I posted this in response to yet another one of the "They are Breaking the Lore by adding Necros and Dragon" threads. Even though giving it its own post wont stop the Lore Mongers from trying to rip the expansion apart I think its is very good information to share on exactly how the upcoming expansion info will fit into TES ESO Lore.
There are a lot of people running around who say they know the lore, but don't actually bother to investigate it, because if they did they would realize just how little they actually know.
Necromancy
It is not against the lore at all for Necromancy to be added, especially in Elsweyr
https://en.uesp.net/wiki/Lore:Necromancy
Let me highlight a very specific point for you from Lore:
Elsweyr
Elsweyr is said to be relatively accommodating to necromancy. The Khajiit are said to show little if any outrage over uncovered graves, and corpses can apparently be purchased in the port of Senchal. Though corpses don't hold up well in the forests, the deserts of Elsweyr preserve corpses for centuries, allowing skilled necromancers to make use of them relatively easily. The way the bodies are buried in the deserts, under only a small cairn of stones, is also ideal for necromancers on the prowl for resources
So if they were going to add a Necromancer Class, Elsweyr is the best area for it to be added.
I was hoping it would be added when they finally got around to doing the College of Winterhold since it is even TAUGHT there, but this will do.
Quoted From Lore: "At the prestigious College of Winterhold, it is even considered a legitimate arcane study, provided it is done discreetly and in accordance with the College's rules".
Dragons
As for the Dragons, as long as there aren't a ton of them and they are mainly Trial/Dungeon based (heck even a single World Boss) then they will fit in fine.
Again, look into the lore before you say they don't fit. It isn't until the time of the Skyrim Game (which isn't until the 4th Era) that they are considered extinct after the dealings with Alduin
https://en.uesp.net/wiki/Lore:Dragons
From Lore:
"Many held the belief that the dragons were extinct. This was not true, as live dragons continued to exist throughout the Third and early Fourth Era. Nomads in the Alik'r Desert frequently spoke of "Great Wyrms" inhabiting its vast wastes, although these claims were never independently confirmed. The Akatosh Chantry hold dragons as their holy symbol, and keep tamed dragons in their "sacred grove". Many ancient legends tell of dragons making deals with other races to protect themselves. According to Brarilu Theran, at least one dragon is known to have laired in the smoking ruins of Vvardenfell after the Red Year, long after the cliff racers were driven off by Saint Jiub."
If they existed through out the 3rd and early 4th it means they are alive during the ESO time line since it is just passed the middle of the 2nd Era, so again, as long as there isn't one lurking at every turn they fit perfectly well in the ESO Timeline
Another bit of info from Lore:
"After being largely absent from the affairs of Tamriel for hundreds of years, dragons reappeared en masse in Skyrim and Morrowind in 4E 201 thanks to the return of Alduin."
Note that they are described as "Being Absent from the Affairs of Tamriel" nothing about them being extinct.
What annoys me the most about all these Lore Mongers coming out of the woodwork is that almost all of them get their info from the Skyrim game. Skyrim takes place in 4E 201, ESO is currently taking place in 2E 583 - Skyrim wont happen for about 1000 years from when ESO is currently happening.
In fact the first game in the Elder Scrolls "Main" series (Arena) doesn't take place till E3 370, over 600 years from where we are now in game. If you include the Extended Elder Scrolls Universe Games the first game after ESO chronologically is still 298 years in the future from the current time line, and that is The Redguard Game.
<Please note each of the lore pages I linked have full reference numbers and citations on where the info was found for people who will think this stuff is made up, so you can look into it yourself>
