You’ve got to remember what happened to the titans and the old gods. We have several spots on Azeroth that have the potential of rising up…if all stars align.
But… you also have to remember that curse of flesh has all but wiped out the original caretakers of the discs.
Lot’s that has happened and so much potential for more.
Lore wise, the machines take Azeroth’s crust, and a bit of her soul essence to produce each Earthen/Mogu or whatever… so we could only use so much of Azeroth’s body and soul before it killed the entire planet.
Looks at the septuplets “Okay yeah, that explains alooooot.”
See I still think if we brought the best Earthen, Goblin, Mecha/gnome, and dwarven engineers along with M.O.T.H.E.R, Tyr, Firim, Maybe the aspects, ect, we could easily repair that facility, improve upon it’s original design and power it up.
It wouldn’t even have to pump Mogu out when they were done modifying it, they could have it create a different construct.
