The Jailer's next target is Ardenweald

My speculation from last July

@Baalsamael-turalyon

This is speculation but:

1. Tyrande’s Night Warrior power is tied to Ardenweald
2. The Winter Queen’s existence is tied to Ardenweald via the Heart of the Forest; the weaker it gets, the weaker she gets, and vice versa, and this Heart is tied to the “lock” on the Maw. (Campagin Questline)
3. Winter Queen/Ardenweald will be restored by Tyrande letting go of her vengeance and releasing its power to Ardenweald

at the same time

1. Excluding Tirna Achiad (Heart of the Forest), there are a total of 9 Tirna Trees (Eas, Glayn, Rowen, Vaal, Scithe, Fenn, Kaithe, Marwol, Noch)
2. During questing, we learn Tirna Noch is “long dead” and they never bother to check it out; turns out the Drust have colonized it and restored the Heart of Tirna Noch with anima for their own benefit
3. There’s a part of Tirna Marwol that is closed off and looks raid-esque.
4. These trees are what allow for reincarnation; they gather anima to feed the Wild Seeds.

And at the same time:

1. On Azeroth, World Trees can be bound to World Trees in the Dream
2. There are non-World-Trees that have Emerald Dream parallels (e.g. Tal’doren vs Daralnir)

Therefore it stands to reason the Winter Queen and Ardenweald-bound Ysera can give their “blessing” to restore Teldrassil.

Also consider Undercity is currently blighted and we are being given a very Forsaken-Scourge-esque zone with a “House of Plagues”.

I thus speculate, and have been, that the end of Shadowlands will lead to most of BFA being “undone”; Undercity and Teldrassil restored.
