Sicarian Ruststalkers were originally devised as cybernetic assassins, sent into the Red Planet's wastes to hunt down feral Servitors and other undesirables excommunicated from the Cult Mechanicus. They proved so effective at their task they were repurposed and militarised into groups known as killclades. Since that day they have fought on the front line of the Cult Mechanicus' many wars. The Ruststalkers of the Skitarii Legions fall upon their foes in a slashing, stabbing frenzy. Their transonic blades blur as they dart and cut like the weapons of gladiatorial knife-fighters, the deadly resonances they transmit bypassing armour as if it offered no more resistance than a hologram.
