  1. Reign of Grelok:
    Horned head - When you draw your sword, Grelok lowers his great horned head and bellows laughter in your face.
    Zombies - As you recover from the stench of the priestly belch, you are told that the priest has fled from his nearby chapel. When Grelok arrived on the mountain, the dead in his cemetery began to rise, and his congregation scattered.
