Decades after Fortune's Favor successfully defeated and banished Marcus the Betrayer, an aging Petravian Calenius is tasked with one last mission: investigating a mysterious crack in the skies above Aedron, and the strange crystal-armored soldiers who've emerged from it. To aid him in his quest, R'issen summons alternate versions of his former comrades from across the threads of time and Fate, each one having lived a very different life from the adventurers and friends he once knew.
