Black Rift (Legends of the Age of Sigmar)

In the Tephra Crater lies the city of Uryx, a once-proud bastion now overrun by the Bloodbound. Anhur the Scarlet Lord means to use the city to open a gateway to Khorne’s own realm and drench all of Klaxus in blood. Only Sigmar’s chosen stand in his way – the Warrior Chamber of Orius the Adamantine, one of many fighting a bitter war of liberation in this region. Their quest is a grim breach the walls and reach the heart of Uryx to prevent a ritual that will bring about death untold. The hopes of all Klaxus rest on Lord-Celestant Orius – his warriors are many, and heroes all, but to triumph he must defeat not only the forces of Chaos but the demons of his own past.
