The races of the Old World all have rich histories and hold ancient customs and traditions that date back many millennia. And in a world of eternal war, these races each harbor ancient enmities. As the races of the Old World continue to seek new means of routing their old foes, Warhammer: Invasion - Glory of Days Past – the fourth Battle Pack in the "Eternal War" cycle – presents them with sixty new cards (three copies each of twenty individual cards) that explore their traditional strengths while developing strategies based around dynamic battlefield phases and the Ambush and Raider keywords.

As ceaseless battles deplete each army's resources, the Dwarfs rely upon the riches of their mines and the talents of a legendary runesmith to forge new defenses. Elite Greenskin Warriors and Cavalry surge forward in an endless tide of violence. Men of the Empire ready to meet them with both Spells and steel, though the forces of Chaos seek to corrupt every army’s mightiest heroes. High Elf Mages seek to protect themselves and their armies by harnessing the Eight Winds, but their dark kin, the Dark Elves, draw strength from their hatred and malice.
