[2971]

I thought before that the black thing ananke mentioned that destroyed weave and was seen a few times before in the tomb was a future sunny, now tho, its all but confirmed it was sunny and nephis surrounding vtb (and at times just sunny and vtb, since nephis has now left the equation)

That leads to the next point, sunny and vtb are what hit weave and destroyed it.

["—The sky seemed to ripple, and a vast darkness escaped from the rifts torn in its azure expanse like a flood. Then, something dark and formless plummeted into the River, piercing the heart of the city — the island where the Temple of the Nightmare Spell stood."] 《Chapter 2934》

Obviously describing sunny surrounding vtb, it makes too much sense since vtb almost lost a wing and lost its equilibrium, ready to plummet into the fissure. The next travel point will be weave, and vtb with sunny surrounding it will destroy it.
