This was not the instant lethality of a strike or a spell. The demon was dying, but dying at the pace that a toxin died things rather than the pace that force died things. Minutes rather than seconds. A gradual reduction of the essence that sustained everything the demon was, the thing that made it Grade Four becoming less and less available as the Null Blood worked through its system.
The demon's eyes were on him throughout.
Not with fury. Something different, the quality of an intelligent creature that had understood, sometime in the last several minutes, what was happening to it and was not able to do anything about that understanding.
He did not feel particularly bad about this.
The demon was a Null demon. Its blood killed things by doing exactly what was being done to it now. The irony of the situation was the most interesting aspect of it from a certain perspective.
He watched the essence level drop.
It took time.
