The City and the Dungeon

The City is an immense metropolis of crystal spires and wondrous magic. Beneath it lies the Dungeon — a vast underground world, source of endless treasure guarded by grotesque and deadly monsters. No one knows where the Dungeon came from, or why. Anyone who dares its dangers must first be transformed into a delver, a quasi-immortal creature defined entirely by numbers. Yet the immortality offered is illusionary: without consuming the crystal found only within the Dungeon, a delver will inevitably die. One young immigrant braves the Dungeon to send money home — and finds much, much more.

Shocked by discoveries deep in the Dungeon, the City prepares to delve even further for answers — but a surprise attack by the subterranean Undercity throws them into chaos, and a massive war erupts throughout the Dungeon itself. Alex Kenderman is recruited by the supreme commander to lend his tactical expertise. He and his party must fight against Underdwellers and the Dungeon itself to obtain victory. But two sinister questions remain: why did the Undercity start the war, and who will win it?
