Game description from the publisher:
The sixth and final Battle Pack in "The Capital Cycle" for Warhammer: Invasion The Card Game, The Imperial Throne puts the focus on the Old World's greatest nation with roughly half of the 60 new cards (three copies each of 20 different cards) dedicated to the Empire of Man.
The Empire of Man is the greatest nation of the Old World, spanning the continent from the southern Border Princes to snow-clad Kislev in the north, and The Imperial Throne reflects the nation's richness and diversity. Imperial players gain a new Hero, Fortification, and Capital Center, as well as other units and support cards. The Empire's allies and foes also receive new units and support cards, including explosive new support cards and a means of making targeted searches through their decks.
