Here is a good fan analysis I discovered (for your reading pleasure) and my thoughts on it, enjoy, and let me hear your thoughts, views and desire. I have woven mine into the source material. Still editing for better presentation, so bear with me if it's a bit rough.
.But what will that mean for the future? both of Elves and of magic - now the biggest hindering block to all the elven groups is gone? Would it bring unity? Excelling to dominate the magic field again? In wow, the elves, in particular night elves always seemed crippled over arcane usage and the negative effects it had on them. Although to the northern Kalimdor group, the biggest negative was the belief its usage would be a beacon to inevitable draw the legion and the end of the world back, its over-use which we now discover was actually usage out of balance also developed a serious problem which had already changed their society from the grace and benevolence that characterised it's nascent stages to haughty and callous amongst it's most noble and prestigious members. A fault that resulted in the reckless use that drew the Legion in the first place. From that era onwards one group would totatlly change its use on magic and it would later cause that group to schism and create an enmity that persists strongly till this day. The heart of this was the effect this imbalance, addiction to some, hunger or dependency to others would have on these two groups. Yet an even greater negative effect would result in the night elves of Suramar who found themselves forced now not by arrogance or indulgence, but by necessity to rely on the arcane even more, exacerbating this issue even further to crippling effect as the excessive use would poison their source and create a deadly and gnawing hunger to which only the flawed source would satisfy.
In the first group, the Northern Kalimdor group, this issue would result in the cessation of magic usage for spells for 10k years, and in the other group who split from them over the issue, in time though they prospered for nearly 7,000 years, it would result in a crisis and catastrophe that would nearly wipe that group out and divide them into two opposing camps as a result of the choices the survivors made. This ofc had a very limiting restriction any serious Elven excelling in both night elves and blood elves both, and their related Nightborne and High elves it would change them too, the former on the verge of bringing about their total destruction by crippling their ability to repel a very recent Legion occupation, would force a journey of an adventurer, and a loving night elf keen on redeeming his fallen brethren to work in concert and finally successfully produce a solution, the fruit of a very ancient and long quest to heal the imbalance within the night elven racial group that went back to the time before the sundering, when it all started
So from WC3 and most of recent times in wow lore HElves & BElves have been dominated by an era of magical crises, but they recently came out of that. Seems that NElves have had an issue for 10k years and only recently braving the arcane front, only to meet NbElves who are introduced with an even bigger more crippling crises than the H/BElves had - makes sense as these elves have been in total arcane dependency for 10k years, as individuals and as people.
We first had an end to the high/blood elf addiction with theTBC Blood elf story and the Sunwell, the divine suffusion curbing their arcane hunger and by association the high elves too. Now we have the nightborne too have a solution that has brought balance eliminating their chronic dependancy, restoring them fully and ofc all addiction now in all Night Elves including Highborne who practice the arcane.
Valewalker Farodin.
The Arcan'dor brings the arcane into balance for all night elves, curing arcane addiction and is able to completely restore and heal all nightborne elves
This has huge implications ofc, especially for the nightborne
But also for the NElves - though they started embracing the arcane again since cata and their long separated and exiled Highborne kin (HbElves') return, some enthusiastically, the older and wiser esp druids would be worried about potential arcane addiction either developing or affecting the highborne. Although I see no record of this worry, because Malfruion himself and Tyrande eventually trust them by allowing them un-restricted practice of the arcane arts, you could imagine that some of them would be nervous... Maiev in her craziest moment downright refuses to trust them, and tries to kill them. She fails ofc, but now concrete evidence that is based in nature, opens the way to seriously boost the confidence of ALL night elves concerning the arcane and working closer and trustingly with arcane night elf groups like the Highborne, the Moonguard and the nightborne elves - the action sof these 3 groups in cata and legion also shows that they can be trusted in terms of moral character, and now the solution means they don't have to worry about arcane addiction.
Prediction 1:
This paves the way for full corporation between nature users and arcane users amongst night elf kind
Theorizing The Future- A speculation;
The last wall, and the biggest stumbling block between Darnassian night elf, and arcane night elves (Highborne & Nightborne elves) is gone. With balance restored, so too should the last fears of going out of control and doing stupid things to hang on to the arcane because of addiction. This paves the way for peace and partnership between the nature based night elves and the arcane based ones with a firm trust that can develop - but does it open the way for peace between the night bunch and the Thalassian bunch ??
With this limitation gone now, it opens the door for all elven kind, but it would seem especially the night elves who had held back, and the Nightborne elves who had been crippled from excelling and progressing further in magical arts, now without imbalance or shunning of nature or Elune. The same goes for the blood elves and high elves, who from the lore I could almost guess were holding back a bit, certainly in recent times.
I'm reading this as they have the experience, the discipline to go much further without harm to themselves, allowing a balance and harmony that can only produce very good things. No more to be crippled, , hurt, maimed or broken by ill behaviour. Will we see benevolent, wise and very magical elves in full balance now?
Possible directon of The Elves from now on?
Blood elves and nightborne seem to be the more ambitious elves, while high elves and night elves seem to be more benevolent. It seems that nightborne makes a nice complement to night elves, whiles High elves are the natural complement to Blood elves, I wonder if this means we will we see the high elves finally shift onto the horde from now on, can they overcome recent squabbles? 7.1 reveals to us the high elves, like the blood elves do not like the night elves at all as we suspected, and the dislike is far older than recent high/blood elf feuding , whereas night elves seem to get along with nightborne even though faction leader Tyrande is initially cold to them- with the arcane addiction and corruption finally cured, it is looking like every reason for the nightborne and night elves to work well together, and once the nightborne who allied with the legion are punished, things should go well as it looks like Fel is now taking the place of the arcane as the one in which they all take issue with. Which helps with inconsistencies as the arcane was always a good source in the lore, and yet was corrupting elves, the ones who had the highest affinity to it, hindering their current development in it in the current timeline
Prediction 2
With that solved this should allow the elven groups to really excel in magic, hopefully taking their place as the Warcraft world's authority on magic, and it is looking like blood elves on one side, and nightborne on the other, because these are the two most advanced groups. If Dalaran continues to dominate the scene, I see one of two things happening, the Elves of both sides playing a dominant role there OR the Elves doing their own separate thing, either together or apart with the Sunwell for the light elves, and the nightwell for the dark-skinned elves, this may mean with the night elves and nightborne on one side and the high elves and blood elves on the other side.
I'm not sure how the horde/alliance thing would work though.
Option 1 is night elf and nightborne on one side, blood elf and high elf on the other - the groups either mixing into 1 body or still keeping their identities, with High elf and nightborne still being unplayable.
Option 2 is night elf and high elf on one side, blood elf and nightborne on the other side - but that leaves friction as night/high don't get along, and gives you 2 benevolent groups - night elf need some ambition, blood elf need some more benevolence.
Option 3 is Nightborne released as a new alliance night elf based race, but in the following expansion, nightborne made accessible to horde, while high elves made accessible to Thalassian race on both sides, and nightborne on both sides too - this means that alliance finally get playable high elves, and horde will get a playable night elven group (Thalassian on the horde side is blood elf)
there are other possibilities, but I think I would prefer Option 1 first, then Option 3 - I really want to see how blood elves would fair against nightborne, new sunwell versus nightwell - I would prefer that to passivity and all hugs, but we'll see?
Changes for High and Blood Elves?
What do you think here? I am thinking that new possibilities between high/blood elves will continue as we see relations improving with each new revelation. High elves and blood elves still have the issue of the Silver Covenant - however outside the Silver Covenant, the High elves have been shown to generally be getting friendly with the blood elves without losing their high elf identity, something that immediately started to show once the blood elves found redemption in TBC with the re-ignition of the Sunwell. Further evidence in Legion shows Vereesa very friendly to blood elves, she genuinely cares for a blood elf in the hunter artifact quest, and he genuinely cares for her, and it also seems she is working well alongside Halduron. Furthermore, Vereesa seems to be getting along quite well with the blood elves too in7.1
And with Alleria's return iminent, this indicates a healing of high elf and blood elf relationships, because Vereesa was the main reason for the conflict getting bloody, especially after Rhonin's death, which is now soley attributed to Garrosh and a few rogue Blood elves working with him.
The other two groups the Highborne and the Darkfallen, while noticeable, seem to be very tiny in number, with the Highborne tied to the night elves and the darkfallen tied to the forsaken. however since the Blood elf DKs are Blood elf tied not forsaken tied, we might see a blood elf connection there, and this the Highborne and nightborne are the same arcane night elf culture, we'll likely see them more connected with them instead too.
Finally I have another question... would you want to see all the elves heal? and if not, will you wanna see HElves and BElves unite again at least, like the NElves and NbElves
