The Death Knight of Maargadum

The Mages have strengthened the barrier around Maargadum Jail, but it will not hold forever. The evil within will gradually grow strong enough to sweep away every obstacle and break free. Alas, heroes who overestimate their strength enter the jail all too often... And when they die, the army of death gains new puppets. Destroy the former priest, now the death knight Maargadum, so that the evil will at least grow quiet for a while.
