“And he felt it.
Rogal Dorn had been feeling it for days, weeks, building up, up, up, rising over him like a black fog, dragging at his limbs, clogging his mind, making him question every decision he made, every order he gave.
He hadn’t had any respite at all, of any kind, for three months. Three months! His sharpness was going now, his reactions were slower. A billion functionaries depending on him for everything, reaching out to him, suffocating him with their endless demands, pleas for help, for guidance. A billion eyes, on him, all the time.
And he’d fought, too. He’d fought. He’d fought primarchs, brothers he’d once thought of as equals or betters. He’d seen the hatred in Perturabo’s eyes, the mania in Fulgrim’s, stabbing at him, poisoning him. Every duel, every brief foray into combat, had chipped a bit more off, had weakened the foundations a little further. Fulgrim had been the worst. His brother’s old form, so pleasing to the eye, had gone, replaced by bodily corruption so deep he scarcely had the words for it. That degradation repulsed him almost more than anything else. It showed just how far you could fall, if you lost your footing in reality completely.
You couldn’t show that repulsion. You couldn’t betray the doubt, or give away the fatigue. You couldn’t give away so much as a flicker of weakness, or the game was up, so Dorn’s face remained just as it always had been – static, flinty, curt. He kept his shoulders back, spine straight. He hid the fevers that raged behind his eyes, the bone-deep weariness that throbbed through every muscle, all for show, all to give those who looked up to him something to cling on to, to believe in. The Emperor, his father, was gone, silent, locked in His own unimaginable agonies, and so everything else had crashed onto his shoulders. The weight of the entire species, all their frailties and imperfections, wrapped tight around his mouth and throat and nostrils, choking him, drowning him, making him want to cry out loud, to cower away from it, something he would never do, could never do, and so he remained where he was, caught between the infinite weight of Horus’ malice and the infinite demands of the Emperor’s will, and it would break him, he knew, break him open like the walls themselves, which were about to break now too, despite all he had done, but had it been enough, yes it had, no it could not have been, they would break, they must not break…
He clenched his fist, curling the fingers up tight. His mind was racing again. He was on the edge, slipping into a fugue state, the paralysis he dreaded. It came from within. It came from without. Something – something – was making the entire structure around him panic, weaken, fail in resolve. He was not immune. He was the pinnacle – when the base was corrupted, he, too, eventually, would shatter.”

“All my life, I have had a reputation for being cold, unfeeling. Some have called me heartless, ruthless, even cruel. I am not. I am not beyond emotional response or compassion. But I possess - and my masters count this as perhaps my paramount virtue - a singular force of will. Throughout my career it has served me well to draw on this facility and steel myself, unflinching, at all that this wretched galaxy can throw at me. To feel pain or fear or grief is to allow myself a luxury I cannot afford.”
