Evil knows no bounds, color, or frontier. As the zombie plague spread, we soon observed that some figures among the Orcish hordes didn’t turn into feral, mindless, killing machines. They were the ones keeping still with gloomy smiles, as their own people were being corrupted. These dark creatures were the necromancers. They caused all of this. The zombie horde is their weapon to spread chaos and seize power. They flee upon being discovered in order to spread the disease somewhere else. Make them your priority target, and kill them whenever possible.
