Alright maggots listen up. I've been given orders from on high to add my own little nugget of goodness in the deliciously evil chaos stew brewing up in here so here it is:

The Unbidden,

An elite, roughly sixty marine strong, force of Alpha Leigonaries. They are led by a Champion known only by the name of Weeper, due to the desgin of his helmet. (its an infant-like face as the central faceplate, but the rest of the helm looks like a serpents head and maw, of course the faceplate has tears on its otherwise placid face) They shall be the silent fist of the Warband, showing up when least expected and dealing the killing or crippling blow to the Dark Covenants foes. They specialize in sabotage and assassination, as well as extended operations within enemy territory. Their wargear consists of mostly the standard, bolters, rocket launchers, grenade lauchers, ect. Vehicles will mostly be areial options like Thunderhawks and such, with some assault bikes for infiltration and rapid exviltration. As for armor, they do have some Terminators for deep striking attacks, mostly for a surprise attack that overcomes the enemy with the sheer force or to cover a botched opperation. Their tactics are very typical Alpha Legion, with mortal spies and cultists and such.

They have no names and their own warband name was actually given to them over time by other members of the Dark Covenant, they are known as the Unbidden because they are never ever requested for, they merely appear. That and most commanders do not wish for their help or company as they are pretty damn creepy, all silent and sneaky. An aura of trechery surrounds them... and yet Xaphuris keeps them around as they are very good at what they do.

Generally they are all veterans of the Long War, each one an experiecned Astartes. They are, as would be expected, very secretive and aloof. So much so, that they do not even have their own names. All of their names are either crypic codenames, or titles of their fearful allies that have simply stuck. They never show their faces, never show emotion, and never give their goals away. Why and when did they join the Covenant? Are they true servants of Chaos or some kind of subersive force of secret loyalists? Dose Xaphuris command them, or simply tolorate their presence as he sees them as conveient?

I await your approval, fellow heretics.
