The survivors of a long-ago invasion have taken refuge in the forgotten underground city of Gravehold. There; the desperate remnants of society have learned that the energy of the very breaches the beings use to attack them can be repurposed through various gems; transforming the malign energies within into beneficial spells and weapons to aid their last line of defense: the breach mages.Aeon's End is a cooperative game that explores the deckbuilding genre with a number of innovative mechanisms; including a variable turn order system that simulates the chaos of an attack; and deck management rules that require careful planning with every discarded card. Players will struggle to defend Gravehold from The Nameless and their hordes using unique abilities; powerful spells; and; most importantly of all; their collective wits.
