As the story in DF keeps unfolding and we are given small tidbits of lore that can be used in the future, I’m also basing my speculation on things said by Devs. One of them being that Sargera’s sword would play a role in the future and how Ion recently said that they work on new expansions one expansion ahead of the one we’re in or the one about to be released.
Usually lore (not just in WoW) is planned even further ahead, even if it might be in a very simplified form. So with this info I can’t help but keep thinking that this is the time to see the rammifications of the events that unfolded in Legion.
During DF, in the Chromie Time quest, we are taken to Ny’alotha where N’zoth whispers to us a few things that my mind quickly associated with the info I’ve mentioned at the start.
" I… know you. What you were. What you will yet be.
You will follow him to the deep places. The dark waters will flow in his wake.
With many eyes, they will see again. They will drink, and be uplifted.
Deeper, deeper its roots will reach. Welcoming our embrace.
Her dreams sing beneath the surface. Our dreams. Our song."
" I… know you. What you were. What you will yet be." - I’m taking this sentence lightly. It’s quite vague. This can just imply that we have met before but we will meet again. “Yet be” implies that whatever roles/titles/purpose we have been given, will change.
“You will follow him to the deep places. The dark waters will flow in his wake.” - This is where it starts getting interesting and begins directly affecting DF’s future for me and where I have more thoughts and speculations.
Raszageth is gone but not without freeing her siblings. Alexstrasza has already showed her fear of having to face Iridikron next. There have been lots of talks of us heading to an underground part of the Isles, which makes sense since Iridikron probably retreated to where the Earth primal forces are strongest.
HOWEVER! This is where Sargera’s sword starts playing a role too. It has been plunged into the ground. While we have defeated Sargeras, been told the sword was dormant during Legion. We don’t know for sure if Sargeras had other intentions other than looking like he was trying to hurt Azeroth. She has bled which led to the creation of Azerite.
Titans “bleed” and from the Blood of Sargeras we were able to create Primal Sargerite but the sword could have also been used by him as a vessel to carry his force/corruption/Sargerita in some capacity and plant himself or his influence underground or maybe he knew exactly where a part of N’zoth was and used his power to break him free or just empower him. Which made N’zoth corrupt the unnamed World Tree in the Nightmare even more.
This may have led to the spread of corrupt waters underground which then spread to where Iridikron is hiding away (The dark waters will flow in his wake) or it had already spread so far, corrupted part of the waters under the Dragon Isles and Iridikron feeling that, retreated specifically to where they might be. Which leads to…
“With many eyes, they will see again. They will drink, and be uplifted.
Deeper, deeper its roots will reach. Welcoming our embrace.” - The Primalists follow Iridikron underground and have now been consuming those Dark Waters and are now corrupted and uplifted. Which have now turned into a stronger, many-eyed version of the Twilight’s Hammer. We deal with Iridikron eventually but not before finding out that the Roots and their corruption has spread more and even deeper and the embrace of the corruption welcomes them. And I think this implies that each subsequent dragon will be more corrupt than the previous one with us dealing with Fyrakk and then Vyranoth lastly. Vyranoth being the closest to the Water elements and peraphs the most affected by the waters.
In nature, trees purify water. We know of the waters of the World Trees being a great source of magic and Life. We also know that Tyrande and Malfurion had been carrying The Sisters’ Tear. They were informed that it would be a “vessel of renewal” and all the Night Elf souls turned it into a World Tree seed. And I think this will be a major plot point, as Merithra becomes the leader of the Green Dragonflight and with the help of Alexstrasza, grow the Seed into a World Tree that is used to cleanse the corrupt waters. And maybe even be used as the new Night Elf home, which has also been hinted at and spoken about.
An interview with Narrative Director Steve Danuser back in November has him telling us that this is an expansion about hope and optimism and he even mentions Sargera’s sword, the world forces stirring in the background and how those never stop even if we have been away in the Shadowlands. And we know those things no doubt have changed the planet.
The Future - "Her dreams sing beneath the surface. Our dreams. Our song." - Just like how N’zoth’s whispers began. I think this just very vaguely hints at the future and what is to come. We have dealt with the Incarnates but not the root cause (no pun intended!) of the corruption. This corruption may now have spread even further than the continents we have visited and can link with the rumours and hints of what’s on the other side of Azeroth and lead into the next Expansion. Where we face N’zoth, see Azeroth being active for the first time as a result and learn about the Titans’ actual purpose and intentions and… Somehow there’s a lot of involvement by the forces of the Void? After all, I think Shadreen is a bit eager to steal some of the spotlight, maybe introduce us to her Master too. Why else would she be bribing us?
