Spider Knights

The Spider Knights are a very secretive Chapter that are believed to be of Raven Guard linage. Though their numbers are a closely kept secret they are believed to be above standard Codex regualted numbers, though to what extent is unknown even to the Inquisitors the Chapter often works with. They are very indipendant from the rest of the Imperium even through they are based within the Segmentum Solar. They specialize in covert operations and surgical strikes, eleminating entire cells of enemy forces as subtley as possible. When on the front lines, they hit the enemy where it is weakest and exploit every chance they get to strike when and where they have the advantage.

The Spider Knights are very weary of Chaos corruption and thus never form close bonds outside of the Chapter, always prepaired to strike down their allies at the slightest sign of taint. They are held by many to be paraniod, misanthropic, and ruthless. However this may simply be due to the Chapters chosen profession, as few agents of espianoge live long without developing a cautious dispostion.

Weapons/Tatics
The Spider Knights often prefer subtle methods to acheive their goals, making use of supressors on all of their bolters regardless of configuration. They also have a tendancy to use simple, yet finely crafted, blades lacking any form of power feild that would give away the Marines position

Homeworld
Arachni VI is a massive Feral world that is one of many habitable planets that orbit the binary stars of the system. Arachni VI is covered in lush and perilous jungle that is only broken up by shallow seas. Arachni VI's dominant lifeform and apex preaditor is the Spider Wolf, a ferocuous and cunning arachnid, this beast far outmaches most beasts the Galaxy has to offer and can kill whole squads of Space Marines with ease. They are highly territorial creatures and each individual patrols vast streaches of land often near a spring or other source of water that prey items have no choice but to frequent. These cunning beasts often lay traps for their prey in the form of webs and pit traps, showing a rudimentary intelegence, though indeed fearsome combatants, the Spider Wolf prefers stealth and ambush to a face to face conforntation, only emerging from the shadows to deliver the killing blow with its venomous fangs and stinger and cart its victem off to its lair to eat at its leasure.

The Chapter takes its name from the Spider Wolf and it plays many important roles in the Chapters culture and pratices, they attempt to emulate the beast in their style of battle and on rare occasions one of the Chapters Weavers will tame one of these beasts and use them as weapons of war.
