Vehement Raiders

As Loyalists
Founded amidst the turmoil of the 21st Founding, the Vehement Raiders were an offspring of the White Scars of unknown origin, that found a likeness to their parent's need for quick assault. As they namesake was, they adopted the position as raiders, crippling Chaos supply lines, luring ork ships away from conflicts, and assaulting the Tau whenever Ethereals were exposed. They served without mercy, often conflicting numbers of Imperial casualties in their raids, which bothered Imperial officials.

To further their own causes, the Raiders abducted their initiates from whatever planet they neared, even if another Chapter had their stake their inhabitants. As if a disrespect to the Inquisition, who always tried to slow down the Astartes, the Raiders took it upon themselves to train whatever psykers they found, despite whatever claims the Scholastia Psykana had.

Nonetheless, the Raiders served in their purpose, mercilessly and unquestioningly. Their actions continued, until corruption in a group of Imperial officers lead the Raiders to wrong strike coordinates, their ground forces butchering thousands of loyal Imperials due to the trickery of Chaos. Seizing the chance to reclaim their lost psykers, the Inquisition demanded the Raiders to serve trial, and return their stock. However, the Raiders, in their stubbornness, refused to admit to trial ("(There are still heretics left to kill--including those who deceived us!)"

- Captain Markellon of the 4th Company ) and continued their campaign, promptly removing themselves from any Ecclisiarchy presence.

These actions resulted in the declaration of Heresy of the Chapter, resulting in a conflict between the Raiders and the Ultramarines, Lion Warriors, Blood Ravens, and White Scars. After many weeks of combat, the Ultramarines lead a fleet in which delivered Exterminatus to the Vehement Raider's home world, leaving the remainder of the Chapter to flee into the Eye of Terror.

Servants of Chaos
Upon their flight, the Vehement Raiders initially found themselves at odds in the miasma of the Eye of Terror, their warriors slowly adapting to the worship of separate chaos gods. For their first decade, they served as mercenaries for greater warbands in the form of a grand company, which slowly diminished as their masters obtained the rights to all slaves.

As the Raiders numbered less than 300 and only three warships remaining, the Vehement Raiders abandoned their servitude and returned independent amidst the galaxy--their old profession as raiders serving them as they began assaulting Astartes initiate worlds. During their treks, the Raiders began breeding some initiates before trying to make them a Raider, effectively beginning crops of apprentices, to further revive their numbers.

Approach to War
The Raiders favor quick, tactical insertions, much like as when they were once loyalists, often initiated with orbital volleys followed by drop pods and Thunderhawks.

The Raiders field numbers of Land Speeders and Bikes, much like the White Scars, though they bear Havoc squads to support any position they must hold for initiate abduction.

Ultramarines
As they were the ones who burnt their homeworld to cinders, the Vehement Raiders hold a particular grudge against the Ultramarines, harassing their recruitment worlds before scheduled initiation season.

White Scars
Cast from their brotherhood with exile, the Vehement Raiders relish the chances to meet their once-brothers, with massive stalemates occurring as the forces constantly try to leave false access points and confuse the enemy, but to little avail. However, Raiders rarely succeed against a group of Company-strength White Scars.

Markellon
The leader of the remaining Vehement Raiders. He oversees a large majority of the Raiders' actions, leading two hundred brothers in his warband, bearing no icons of Chaos worship. Markellon commands the last remaining land Raider in the Vehement's armory, and is always found astride it at the spearhead. He is a tactical and precise leader, constantly watching the White Scars for tactical improvement or changes that might benefit the Raiders in their battles.

Ferdaid
The Champion of the 2nd Raider's Warband, often scheming with his league of Chaos champions whom consul him in most of his actions. Ferdaid claims to be a worshiper of Chaos Undivided, but takes a particular interest in the works of Khorne. Some members of his warband consider him a greater leader than Markellon, putting him at ends with the legion's commander. Ferdaid wears old terminator armor, supposedly stolen from a dead Ultramarine.
