Dreadwing
The most feared branch of the Hexagrammaton, the Dreadwing was called in when the total annihilation of the enemy was necessary. Its members were masters of massacres, purges, and the deployment of Exterminatus-class weaponry. They also specialized in using terror as a weapon. Far from dumb brutes, it fell to the initiates of the Dreadwing the caretaking and maintenance of some of the most dangerous technologies to exist within the Imperium, they were the First Legion's "dirty tricks department", with all sorts of secret and very nasty gear that they really shouldn't have - really shocking stuff, like radioactive plasma weapons, vortex artillery, and phosphex flamethrowers.
The Dreadwing was an amalgamation of the earlier Host of Bone, maintaining many of its Scandinavian ceremonies and titles despite the influx of recruits from Caliban, along with the Host of Stone, renowned for their expertise in defense and siege warfare.
Its members were known to be grim but capable of safely operating some of the most dangerous technologies in the Imperium. Its ranks included most of the Legion's Destroyer Squads and Interemptors but also a large number of Techmarines and Apothecaries> In its sealed vaults rested the least stable Legion Dreadnoughts, those whose minds had eroded to the point of savageness.
When despair and loss forced the ideals of the Great Crusade to be rejected, the Dreadwing became the host for those warriors who were allowed to use their psychic powers by the primarch.
Notable Members
- Farith Redloss - Voted-Lieutenant of the Dreadwing (takes out a World Eaters Leviathan Dreadnaught with his axe). Was sent a message by the Watchers to get the Dark Angels to return to Caliban before it was too late, but gave up arguing when weighed against his loyalties to the Lion and his friendship with Holguin.
- Marduk Sedras - one of the oldest members of the Astartes, being 250 years old by the time of the Horus Heresy. Decided that command wasn't for him, so passed up the job of Master so he could stay on the front lines. Has a massive blade called the Death of Worlds, composed of fragments of adamantine from each world he has participated in the destruction of. Needless to say that the sword is now so large and heavy that only the strongest members of the Legion are able to actually carry it!
Unique Units
The Dreadwing are represented on the tabletop by the Dreadwing Interemptor, essentially what you get if you took a Destroyer Squad and decided to give them rapid-fire plasma weapons.
They also had a Terminator unit called the Naufragia; terminators armed with phosphex incinerator cannons, though they have not been seen on the tabletop.
