Fulgrim vs. Avatar

No, this was a creature with a power to match his own, a terrible god-like being that bore the heart of its fading race within its iron breast. It would not be baited or riled with petty insults, it was a warrior creature with one purpose and one purpose alone: to kill.

Such a one-dimensional aspect made Fulgrim sick, for what was life and death but a series of sensations to be experienced one after another. Without sensation what was life?

A wild exultation filled him and his senses seemed to rise to the surface of his skin. He felt every tiny gust of wind as it wound past his body, the heat of the creature before him, the coolness of the planet's atmosphere and the softness of the grass beneath him.

He was truly alive and at the height of his powers!
