What's Wrong with Me, the King of the North, All My Subordinates Are Undead?

Lund III, the King of the North, was besieged by 200,000 orcs in a desperate city. The thirty thousand soldiers and civilians in the city were about to run out of food and fodder, and the southern countries stood idly by. The only way to survive lies in the taboo legend in the far north of the continent - the "Death Raider" who talks to the dead. In exchange for a glimmer of hope, he opened the door to the underworld at the cost of his throne, his memory, and a thousand years of loneliness. When he led the silent undead army back to the world and defeated the orc craze, he discovered that the real test had just begun... "I saved my country, but became a heretic in the eyes of the living."
