Barky was Xykon's pet dog when he was a small child and had not yet chosen the name he would be known by when he made the decision to become an evil sorceror.. He died due to an unknown cause. As the small boy wept over his loss, a surge of energy emitted from his body, and the dog was 'brought back to life' as a zombie. Seconds after its reassembelence of undeath, the dog devoured a bird. After this, the young Xykon developed a taste for death and gore.
