While Centaurs are somewhat common amongst the species of Mythoss, their Shadow cousins have long been nothing more than a horrific memory from the First Age of the Realm. As Poxxus returns to Mythoss, he opens the Nethergate and allows a stampede of these nightmares to terrorize Mythoss once again. As the deadliest hunters in the Circle, Poxxus sends his Shadow Centaurs to seek out and slay the leaders of the Convocation. Breaking into the Tower of Bassylia, the Shadow Centaurs hunt their prey, but a familiar-looking Necromancer, and the spirits of the scholars who once defended those halls of learning, stand resolutely in their way.
