Arco-flagellant

[[File:Arco-Flagellants.jpg|330px|right|thumb|[[These guys and Eversors Assassians would be great friends, or having a rivalry that sparks a film franchise lasting four decades. An Arco-flagellant is the result of a rare case where a filthy heretic is deemed redeemable enough to be inducted back into the ranks of the Imperium. Of course, such a severe crime is often not left unpunished, and the Ecclesiarchy are sensible enough to punish them in the most appropriate way possible: by turning them into living weapons.

Arco-flagellants occupy a weird ethical and moral ground within /tg/: on one hand the idea of turning convicted criminals into biological weapons would make most modern governments shit themselves... on the other hand, these are traitor heretics we are talking about and sending them to a warzone to redeem themselves of their past wrongdoings is quite noble in a way. Plus, the fans know that the souls of those people really are on the line and a short time of extreme suffering in life beats an eternity of suffering far beyond mere definitions in the Warp.

Arco-flagellation

The process of arco-flagellation is a method of penitence administered by the Adeptus Mechanicus, but appointed by the Ecclesiarchy. It is used to punish any heresy not terrible enough to warrant immediate execution. The point of such extravagant punishments is to physically expunge the sin from a heretic's soul so that they may strengthen the Emperor when they die.

In arco-flagellation, the heretic undergoes extensive physical surgery and mental reconditioning, turning them into frenzied berserkers. The guilty person is lobotomised and his prefrontal cortex is fried, eliminating any possibility of higher-level thought. Notably, this part is usually done at the very end of the surgery so they can feel the pain of the punishment. He can be implanted with a variety of weapons, such as cutting claws, pneu-mattocks and electro-flails. The Arco-flagellant is fitted with a sealed pacifier helm containing implants and drug-injection pumps that connect into the cerebrum and spinal cord, which keeps them in a calm, barely conscious state. When in this mode the Arco-flagellant's mind is filled with sacred images and verses, such as symbols of the Ecclesiarchy, pictures of Saints and looped hymnals and prayers, which enter directly into the heretic's subconscious. The helm can be deactivated by means of a trigger word, releasing inhibitors and unleashing the full fury Tard Rage of the Arco-flagellant. Another trigger word activates the pacifier helm again, rendering the Arco-flagellant passive once more.

Arco-flagellants are almost unstoppable once activated, as the combat drugs and painkillers shot directly into their spine turns them into roided out maniacs, making them heedless of most injuries they sustain. They are literally Imperial Khorne Berserkers. Arco-flagellants are normally used by the Ecclesiarchy's fighting forces in suicide attack units, because if running blindly into heretical lasgun fire doesn't kill them, the combat stims making to flagellant's body shit itself to death due to the strain of holy combat usually does. However, an Inquisitor can request (or demand if they are confident enough) that a Cardinal turn over an Arco-flagellant or two to their authority. An Arco-flagellant is not a subtle weapon, and they are much appreciated by the more bloody-minded Inquisitors, who are not afraid of some collateral damage and a few innocent casualties.

There are also incredibly rare Arco-flagellants made from Blanks called Serpahs, which are used by Inquisitors serving near warp rifts or guarding the most important Inquisition prisons and facilities.

The moral? If you're going to commit heresy, make it bad enough you're just killed on the spot or be ready to kill yourself.
