Strigany

The human empire of Strigos worshipped Vampires as Gods, but their Undead deities couldn’t save them from the might of butchering Greenskins. When the few escapees staggered north into the Old World, the stricken people met a wall of hatred from the other human tribes, but they had nowhere else to turn.

They wander there still, now calling themselves the Strigany, and are hated no less, even though the centuries have erased the memories of their blood-soaked empire from the minds of their countrymen. Mirroring the rootless land caravans of their people, the Strigany meander up and down the Reik in small boat communities, moving from one persecution to the next. Their dreary, poorly maintained vessels are often moored far from civilisation, where they prey on the superstitions of passing riverfolk by selling charms and wards for whatever coin they can. They are a desperate people, often clinging to the half-forgotten legends that say that their ancient Vampiric masters will someday return to lift them from their pathetic lives. As rumours of these throwback beliefs ripple outward and are heard by outsiders, the continued Vampire worship doesn’t help those Strigany who are trying to move on from their past. Rather, it ensures that their persecution at the hands of outsiders continues. The Strigany are quickly blamed for any local problem without a more obvious culprit, and over-zealous Witch Hunters are all too eager to accuse them transporting diseased Undead in their rotten barges. By the time their innocence is proven in these cases, their boats are already burnt to the waterline.
