Bellular keeps making this absurd statement that we, the players, introduced the void to the Emerald Dream, because of that void flower in the cave at the end. How on earth did he reach this bogus conclusion? Xal'atath speaks of it like "almost gone, as if it never existed", the damn thing is called remnant of the void. It's more implied that it's the original seed of corruption that Yogg Saron planted to create the Emerald Nightmare, and that's all that remains of it.
I keep asking it on youtube, and never get a response.
