Marvel re-invented the X-Men in last fall’s House of X events series, and now that bold new era of X-Men has led to its first big crossover event, “X of Swords”. The official kick-off to the new X-Men event happens in X of Swords: Creation #1, which lays out the epic scope of the X-Men’s upcoming war with dark inhabitants of another dimension. However, in laying the groundwork for that battle, writers Jonathan Hickman and Tini Howard also expand the mythos of the ancient Marvel Universe in a way that is also quickly expanding the scope of Marvel’s Mutant Culture.
