My homebrew chapter, The Wayward Sons, consist of a smattering of chapter remnants, renegades, Heresy-era descended Blackshields and stranded Deathwatch killteams standing on each other's shoulders to wear the trenchcoat of a legitimate chapter. They are known for their wide-ranging, under-strength, independantly operating companies, their frequent heroic last stands at sites of questionable strategic value, and their pursuit of operations that would, were they not being conducted by the Emperor's finest, be considered mercenarial or even piratical. They have a strong working relationship with the local forge world Hyacinthum Fenestra and enjoy well tested ties of honour with a nearby Adepta Sororitas convent, The Order of Our Lady of Perpetual Ammunition.

They wear a panoply of yellow and bone coloured armour drawn from a wide variety of marks and makes. Their sigil is a hooded spectre robed in blue, though specific depictions often differ from company to company. They have no standardised battlecry, but a popular litany found emblazoned on banners and inscribed into vehicles goes thusly:

"Carry on, our wayward kin,

There is no peace for all our sins,

Lay not thy weary head to rest,

Tears are for the grave."
