Warhammer: Age of Sigmar - Harrowdeep

At the heart of the Realm of Shadow, there lies a place of deepest dark. A cold and ancient labyrinth beneath the ocean bed, where strange halls echo with the sounds of death, and shadow-magics lurk in every nook and cranny. Whispers of its existence haunt the port taverns, along with a rumour that once dragged down those watery depths, there is no hope of escape.

But there are those whose fate has entirely been sealed. A band of Stormcast-errant on a mission to discover the whereabouts of missing fleets; two pirate captains, vying for power on the seas; and a pair of priests on the hunt for a potent weapon. All have fallen prey to this sunken hell, and to survive, they must preserve their sanity. For those above will forget them. The wailing of the wind will smother their cries. And in every waking moment, all they will know is the horror of Harrowdeep.
