Each time you use Ky'veza's Treacherous Transmitter trinket in the open world, it has a rare chance of summoning an Ethereal mob that drops a toy to turn you into an Ethereal. But the important thing here is said mob's name: Ethereum Void Reaper.
So unless this is a complete red herring, we're not dealing with the Shadowguard, or a new villainous faction- we're fighting the original Ethereal villains introduced all the way back in Burning Crusade: the Ethereum.
Which also makes their agenda clear, barring any major changes that they've went through since we last fought them. The Ethereum are K'aresh's former ruling class, and are completely obsessed with getting revenge on Dimensius and his forces, no matter the cost. They consider anyone who refuses to join them an enemy, and worked to "become Void" themselves for the power they need.
So whatever they plan to do with the Dark Heart, it's most likely part of a plan to kill Dimensius. Perhaps they want to drain his power to weaken him, or empower themselves, or just use it directly as a weapon somehow; but killing Dimenius has been their clear end goal ever since Burning Crusade.
Also, on a somewhat related note, the Ethereals are pretty well-suited to have a bunch of sub-factions just like Undermine's Cartels. They could give us different rewards for the Protectorate, Consortium, and a couple new groups to flesh out their society even more.
