The game features heavily armored fantasy warriors, magical creatures, and elaborate armies of painted miniatures that players command in strategic tabletop battles.

Game Setting and Factions

The Age of Sigmar is set in the Mortal Realms, a fantasy universe featuring eight interconnected magical realms.

Major factions include the Stormcast Eternals (warriors of lightning and order), Chaos forces representing darkness and destruction, Death armies of undead creatures, and Destruction forces of bestial and primal creatures. Each faction has extensive miniature ranges and deep lore that supports the broader narrative of the setting.
