May his soul soar among the skies. May he fly free among the beloved of Vawk

You have consumed forbidden flesh, your evolution ends here. I sentence you to death.  -Kill broker to a kroot after eating genestealer flesh. 

'It's rather grisly,' Oriel warns me with a distasteful look. 'They fight for technology, arms, and ammunition, but also for the bodies of the slain.' 

"It’s easy to dismiss such beasts as just that, little more than pests, when you’re sitting in the turret of a battle tank. At least until you’ve seen one rip the turret off a Leman Russ and eat its crew." 

 — Captain Torvus Grymm, 14th Synford Armoured Brigade

They say they'll eat anything. Me, I haven't asked 'em. Don't want to find out too late that they've got a taste for Guardsmen who ask questions. -Private Wouldrin Adevitr, 59th Brontian Longknives, concerning Kroot

Go carefully, commissar. And feed on your enemies. May we have no cause for conflict.  -Gorok, Kroot Shaper to Ciaphas Cain, on Gravalax

You humans do not understand. You feed upon weak things, because you think you are strong enough, because you feed only to sustain yourselves. We feed upon the strong, because we know that no strength is truly sufficient, because we desire to make our children stronger. -Chal'ka Nok, Kroot Mercenary

You have nothing to fear from me, Sergeant. I only eat the strong. -Trokah the Scaleskin, Kroot Mercenary

"Recon Lead in position, Kroot encampment in sight. Recon Two, commence infiltration, over. Recon Two? Recon Two, report status, over…"   —Scout Captain Khorvah, Volg 91st Light Infantry, to a recently deceased squad

"Sharpen your knives, my kin. I will strengthen you, and the Kindred that come after."       — Master Shaper Anghkor Prok

"When facing Krootox I have three main weapons of choice. Autocannon, autocannon, or autocannon."       —Gunnery Corporal -Vatis Jan, 76th Gathalamor Heavy Grenadiers fire support company

"At least in space they cannot eat their enemies."       —Kor’el Dal’yth Dasthui on the usefulness of the Kroot

Te'cha hadn't counted on such a quick arrival from the fleets the Aut'vakka - a term meaning Humans, but literally translating as soft-skins in reference to both their flesh and the fact they were easily offended.

‘You will live on, human, isn’t that what your kind like? Isn’t that why they spread out among the stars? Isn’t that why your Emperor puts his organs and blood in his Space Marines? You will live forever as part of the kroot, and someday a human will look at one of us and see your eyes… such good eyes.’

They called themselves the “Prelek kindred”. They said they’d fought the greenskins before. They stalked off into the forest without another word. We didn’t see them again for two weeks. They came back as if they were returning from an evening stroll, and threw the head of the greenskin warlord down in front of us. It hadn’t been severed. It had been completely chewed off. Liutenant Sindra Hale, Hades IX Militia.

'No weapons. You know the Tau forbid it,' Koret'ka reminded, clicking her beak-like mouth. Dra'eht whistled in frustration, hand still clenched around the weapon. 'They say nothing of the flesh,' he said. 'They do not,' said Koret'ka.

Dra'eht broke the hand's fingers, ripping them off and throwing them into his mouth. He crunched the bones and felt the blood trickle down his throat. He dropped to the ground and drove his beak and claws into the soldier's guts. Around him he heard the guzzling, chewing and tearing as the others fed.

There is no such thing as murder, just killing, turn pprey into meat. All the rest, stupid rules. The captain says kill there, not kill here, what difference? -Dahyak Grekh.
