While the Primal Elements [The First Ones, The Ancients] Are and always Will Be, there is one of the Ancients that was indeed murdered; millennia ago. And it was by his death that the detriment of being Heartbound was discovered.
There is a process in place, to this very day, that were one to die, all [along with any others bound to them] would die. And this is simply a thing that cannot be allowed to happen. As there would befall such an all-encompassing Chaos, regardless the dimension, to the all that is known of the entire universe. An act even the foulest of enemies would wish not seen happen.
But--- were there some so inclined to wish the above-mentioned Antagonists dead, their organic dimension head stones might read:
Here lie the physical remains of Jealousness, Ruthlessness, and Malice.
Remember them not with fondness lest it be forgotten the havoc they wrought.
