It is mentioned here that there may be a Seventh Power. I like to think that the Seventh Force is Fate due to the abilities of this boss
https://wowpedia.fandom.com/wiki/Fat...:_Scrying_Fate
I think that just like the Eternal Ones is the Pantheon of Death or the Titans are the Pantheon of Order, the First Ones is the Pantheon of Fate.
But what if this force also has an opposite?

It says here
'' If truth, what would this say of mortal souls and their potential?
And if the six (or seven, or ... excuse my imprecision) each vie with one another to claim it, could they be driven by the unconscious knowledge that there exists some other force outside our understanding that seeks it as well? ''
6 (or 7) forces are fighting for reality, and perhaps there is one more. That is, if the Broker is right and 7, not 6, forces are fighting for reality, there may be anothen one (8) force.
What could 8 force be? The opposite of Fate? I like to think that 8 power could be totally Oblivion. In the Darksiders universe there is the world of the Abyss in which there are all sorts of terrible monsters live and sometimes they fight on the side of the Hell. But there is also the plan of Oblivion, absolute nothing, anyone who gets there immediately ceases to exist. I think it would be interesting if something like that was in Warcraft. Yes, I know that we already have a Void, but this Void is also synonymous with Darkness / Shadow and is the opposite of Light. I'm talking about absolute nothing. This power may not even have its own Pantheon or army, this power can be a power and a being and a plane (like the Shadow Lands or the Twisting Nether), which simply seeks to destroy all other forces.
