The Black Flood is an estuary of the Sea of Chill, south of Naggarond. Low-lying and boggy, it is a stretch of less populated Dark Elven territory between Naggarond and Clar Karond, with Hag Graef the only major settlement to be found here.
Built back from the estuary at the bottom of a dark canyon, Hag Graef is Naggaroth's second city and possibly its most unsettling. Its eight black towers rise from the canyon floor like the ossified remains of some loathsome cephalopod. Between the towers are strung walkways, platforms and bridges of every shape and size. Some are fashioned from withered timber and soot-stained bone, others are crafted from jagged stone or woven from the silk of monstrous spiders. Sunlight never reaches its walls, and it altogether has the aspect of some immense and awful cave creature crouching in the cold dark.
The rocks below Hag Graef are honeycombed with mines and quarries that are, in turn, threaded through with chain gangs of slaves who claw iron and jet-black stone from the belly of the world. This is the most miserable of existences, toiling far from any natural light, starved on all but the meanest food and chilled to the bone by the piercing wind that howls through the tunnels. Even after death there is no respite - the mines are riddled with veins of warpstone, whose baleful power animates the dead and keeps them labouring until they collapse into piles of worn bones.
Driven by its mines, Hag Graef is a very wealthy city. Its riches and cramped, upsetting conditions in turn make this one of the most fractious places in the Dark Elven empire, with murder, spiteful reprisal and intrigue even more rife than it usually is amongst the children of Khaine. It is so prosperous, in fact, that its armies and influence overshadow even those of Naggarond. So eager are Hag Graef's people to escape their abyssal home that the forced conscription present in other cities is completely unnecessary here. Indeed, over the centuries, Hag Graef has earned a reputation for producing, if not the most disciplined fighters, then certainly the most desperate. The city's mercenary rulers, ever eager for profit, have taken to selling warriors into service elsewhere in Naggaroth, taking with it the opportunity to infiltrate spies wherever they can.
