That's right I've taken together all clues and thought about all possible outcomes to see where future expansions will take us.
So essentially in a nut shell...
9.3 = War between Life and Death
10.0 = Restoration of the Dragonflights
11.0 = Climax of the Cosmic War between Light and Void.
Shadowlands
So SL pits us against the Cosmic Force of Death. The Jailor's MO is to use the power of the Maw to swallow Azeroth's World Soul. Now with the wheel of Death broken, how do we mend the damage caused by the Jailor's agents. Well, as stated by the journal describing Death's efforts to infiltrate all the cosmic forces, Life is the prime foil to death.
Who do we know has the most affinity to Life on Azeroth? The red Dragonflight and Alexstraza! On top of this, the reason why Bolvar is the way he is was due to Red Dragon fire back in Wrath. Bolvar must have some sort of latent life magic in his being while simultaneously being connected to the helm of Domination. There's a reason why Bolvar is the Key Lore figure of SL. I don't know how it will ultimately play out, but I do know the Red Dragonflight will be involved.
After saving Azeroth from the forces of Death, and with the forces of the Void on the horizon, It is clear that the Dragonflights will be needed to fend of this Evil just as the Red Dragonflight was a major fighter against Death.
As we all know, The Aspects and their Dragonflights lost most of their power after Cataclysm. Now during BFA, alternate and residual draconic power was used to further empower the HoA. What if there was more?
If you guys recall, one of Wrathion's servants name dropped the Dragon Isles in some quest text during BFA from an island expedition quest drop. This is the first ever canonical mention of the Dragon Isles's existence in Warcraft.
What if the Dragon Isles hold the key to the return of the Dragonflights? Enter...
10.0 New Continent, the Dragon Isles.
The heroes of Azeroth and the Dragonflights have journeyed to the lost Dragon Isles with the ultimate goal of reviving the flight's lost powers to help against the inevitable threat of the Void. However, the flights, the Horde and the Alliance aren't the only one's seeking the Isles power. The
Twilight's Hammer has returned with leadership from beyond.
Their MO is to use the Isles to revive
Chromatus, a perfect Chromatic Dragon created by Nefarian. For those who are unaware, this is Chromatus
https://wow.gamepedia.com/Chromatus
Chromatus will obviously be defeated btu the Twilight's Hammer's master will soon reappear as a revived
Sinestra! During Legion, it is heavily hinted that Sinestra's is alive somewhere in the great dark beyond. Now she has returned to use the Dragon Isles and restore the Twilight Dragonflight and herald in the Void Lords.
After her defeat, and the restoration of the flights, Nozdormu has a breakdown at the power displayed by Sinestra and her Flight. How can we possibly stand a chance against an
infinite threat as the void. Well we must simply become
INFINTE ourselves.
Nozdormu's sanity shatters. With his power restored, he shatters the Timeways, creating the Infinite Dragonflight and turning into Murozond, fulfilling the prophecy from Cataclysm's
End Time dungeon.
The final boss of 10.0 is the Aspect of Time himself.
Murozond attempts to create an infinite army made up of infinite possibilities of Azeroth's greatest Heroes. The final raid could be made up of AU versions of major lore figues.
No time travel though! They are the result of Murozond's power and disappear once defeated.
After we defeat Murozond and restore the timeways, Murozond unleashes one last desperate attempt to protect Azeroth against the Void. However, we the Heroes are unaware of what he has done.
11.0 New Continent
K'aresh
After the defeat of Murozond, all seemed well. Perhaps his last ditch effort failed? Meanwhile, Stormwind is visited by what appears to be a group of Lightforged Draenie led by none other than Yrel.
Now from here, there will probably be a ton of lore details and what not. However, I believe this will be the driving force of the story...
Yrel will first appear to be benevolent and will attempt to recruit the forces of Azeroth against the void. They successfully recruit the Scarlet Crusade. After sensing the Sunwell's power they attempt to recruit the Horde by using AU Garrosh while Yrel attempt to recruit the LFD and the Vindecar.
Their efforts will turn ugly after the Mag'har get involved and Yrel discovers Alleria and Locus Walker's existence. They believe they can use the latter pair to locate the Void's Strongest physical place of power in the physical universe, destroy it and secure the Light's victory over the Cosmos. They will abduct the two and use Locus Walker to take them to
K'aresh. The home world of the Ethereals and the last known place the Void actively affected in the lore.
From here who knows what could happen. But Key lore figures I'm sure will be a part of it include...
Turalyon
Alleria
Locus Walker
Xalatath
Azshara
and Anduin as the Child of Light and Shadow from the prophecy.
So, have I watched one too many Pyromancer videos? Does this theory hold water? You be the Judge.
