Killing the Death Corrupted Argus sent him to the Shadowlands so killing a Void Corrupted Titan probably would send it to the Void.
The Void Lords managed to get what they wanted and now they have something with the power of creation in their own Realm.
The Void Lords originally only had the power to reduce all to Nothingness as the Chronicle called the Void a vampiric force that would consume all including itself but with their Titan that Sargeras sent to them they now have the power of Creation they so desired which most certainly is providing inspiration to them.
The existence of the 7th Cosmic Force is likely to resolve the need for a Cosmic Force to embody the Inability to Create. The Void used to fill that niche but thanks to the Nathrezim’s meddling Reality needs something else to fill that niche.
It’s probably the Devourers. Without the power of creation they need to feast on anything they can get their teeth into. The only resolution is to give them a Titan World Soul sent to their Realm.
The 7th Force would get a Name after that I dare say.
