Manual stim

The numbness bit at Lucius. He looked to the pressure plate on the underside of his vambrace, the mechanism to control his stimulant rack. His mind wandered to the second of the chemical cocktails the Primogenitor had given to him.

Fabius had told Lucius that it had been derived from the adrenal glands of a xenos breed bioform that had only just appeared in the outermost reaches of the galaxy. *It has yet to make its presence fully known, but when it does…* Bile had said with a rasping laugh *…that will be a singularly fascinating time.* The Primogenitor had called the serum ‘tyrphous’.

A press of the pad sent the oily claret compound into the injection system, and then into Lucius. He did not feel it enter his blood, as he had with the *serpentin*. In fact, he did not feel anything different at all.

Nothing happened. Lucius felt no rush of sensation, no building heat or sharpening of his senses. The Hellions were close enough for Lucius to see the severed heads hanging from their belts, yet his limbs were still leaden with numbness.

(...)

Lucius slammed the eldar against the ground and stomped down upon his head. His hoof crushed the alien’s skull flat, spraying the Eternal’s face with hot blood.

The tyrphous came on hard enough to make Lucius gasp. His flesh came alive. The pupils of his eyes dilated to glistening pools of oil ringed by the thinnest circle of bloodshot green. The entirety of Lucius’ mind was bent around a single impulse, a hunger the likes of which he had never known.

He needed to kill more eldar. He needed to kill them *all*.

Lucius ceased to think. He just reacted, killing again and again as if in a trance. Eldar Hellions fell in screaming agony, to his blade, his lash, his bare hands and teeth. The stimulant drove him on, faster and sharper, compelling him with a yawning void in his core that would destroy him if he did not fill it with a legion of butchered eldar.
