There was power boosted Cho’gall, but it’s not like he should be able to spawn tentacles by his own. Yogg and C’thun were pacified. N’zoth was still locked pretty tight.
But we still had those giant flesh-mouths in zones, who was the central mind that spawned them? Was it even revealed? Was it really just N’zoth (cause he’s the only active candidate)
Kind weird that he was able to open some big (giant) mouths with monumental tentacles in Twilight Highlands, while being completely free in BFA all he did was just glue some eyes on statues
Those mouths aren’t N’zoth’s mouths. They are just some big minions.
The one in Twilight Highlands is called Iso’rath. Dragon Soul had two more called Shu’ma and Go’rath (named after popular Marvel Comics villain Shuma-Gorath lol)
