Marvel's Legion of X follows Kurt Wagner, aka Nightcrawler, as he searches for brand new ideas of justice on the mutant-island Krakoa. Enlisting the assistance of David Haller, aka Legion, the pair assemble The Altar: a bubble-reality contained within the dreaming psyche of Legion and adjoining to the Astral Plane. Nightcrawler has been investigating a rogue body-hopping mutant that has been wreaking havoc on Krakoa. Simultaneously, the Arakki mutant Weaponless Zsen has been tasked with discovering a fugitive Arakki god. Written by Si Spurrier with artwork by Jan Bazaldua, colours by Federico Blee, letters by VC's Clayton Cowles, and design by Tom Muller and Jay Bowen, Legion of X #5 brings a bittersweet and climatic ending to the sequence' first arc.
