A handful of Space Marines and Astra Militarum defend a dying world against the walking dead… but things are about to get worse, for the Death Guard are coming. Lystra is a hive world, with a population of billions… or at least it was. Now Lystra is a corpse, overrun by the walking dead, with just a small force of Astra Militarum and a handful of Space Marines defending against the numberless horde. Exhausted and an inch away from destruction, they hold against the tide… but things are about to get worse, for the Death Guard have noticed Lystra.
