Xyz Dimension

The Xyz Dimension (エクシーズ次元, Ekushīzu Jigen) is a dimension in Yu-Gi-Oh! ARC-V, where Xyz Summoning originated. The city of Heartland was attacked by an army of Duelists from the Fusion Dimension's Academia, resulting in large amounts of its inhabits being turned into cards. The survivors organized themselves into a resistance, counterattacking using the same method.
