The Necro-Industrial Revolution [Kingdom Building]

The Holy Church decrees that all necromancers must burn at the stake. John Frost-Grip just hopes his skeletons can shovel enough snow to put the fires out. When Jack woke up in the frail body of a northern lord, his first thought wasn't about world domination. It was about surviving the week. Winter is howling, the local coal mine has collapsed, and his starving peasants are packing to flee into the frozen wasteland. Worse, Jack's new body is slowly freezing from the inside out due to an untamed Grey Core—a forbidden well of death magic. But Jack used to manage logistics, and he knows an untapped labor force when he sees one. The bones of his ancestors are just resting in the crypt, doing absolutely nothing. It’s time they earned their keep. Armed with a literal skeleton crew, Jack is going to kickstart an industrial revolution. He doesn't want an undead army to slay the living; he just wants them to mine coal, build runic greenhouses, and run a steel mill. But as a thriving, magically heated utopia rises in the harsh north, the greedy lords and holy crusaders of the south will come to claim it.
